How to Plan Both Sides of a 3D Graffiti Practice Train

A two-sided graffiti practice train creates a different composition problem from a flat sketch, sticker or single display panel. You are not only deciding what to paint; you are deciding how two pieces will relate across one physical object.

The two sides can carry matching versions of the same name, separate lettering studies, a piece and a character, or one painted composition paired with the original monochrome design. None of those approaches is automatically better. The right choice depends on what you want to practise, how the train will be displayed and whether you want the finished object to read as one project or two distinct experiments.

This guide uses the Stockholm Graffiti Practice Train from CHROMATICA City Series 11 as the working example. It is approximately 20 × 10 cm, 3D printed and finished with direct UV-printed details. Both sides are available as painting surfaces designed for acrylic paint markers, and a platform-style display stand is included.

What a Two-Sided Graffiti Practice Train Lets You Explore

A paper sketch usually gives you one defined viewing direction. A physical train asks you to think about sequence, rotation and display. The viewer may see one side first, turn the object around and discover the second side later. That makes the relationship between the two compositions part of the artwork.

You can use the two sides to investigate several kinds of variation:

• Letter structure: Paint the same word twice while changing width, lean, spacing or letter connections.
• Color: Keep the outlines consistent but compare warm and cool palettes.
• Hierarchy: Make one side lettering-led and the other character-led.
• Complexity: Develop a direct, readable version on one side and a more experimental version on the other.
• Continuity: Treat both sides as chapters of one visual concept.
• Contrast: Use the surfaces for two unrelated ideas without forcing an artificial connection.
• Original-versus-painted comparison: Paint one side and preserve the other in its supplied monochrome state.

The useful constraint is that both results occupy the same object. Even when the pieces are unrelated, their scale, placement and overall density will be compared. A very open composition on one side and an edge-to-edge composition on the other can make the train feel intentionally dual—or accidentally unresolved. Planning helps you control that difference.

Inspect the Train Before Planning Either Side

Do not begin by forcing a sketch made for a generic rectangle onto the train. First study the actual object from both sides. The printed visual information and the physical form create interruptions that can either support your composition or compete with it.

Place the train on its included stand and look at it from the distance and angle at which you are likely to display it. Then review it more closely. Identify:

• the main uninterrupted areas available for letter bodies;
• printed doors, windows and panel indications;
• changes in the physical surface or silhouette;
• details you want to keep visible;
• details you are comfortable integrating into the piece;
• areas where narrow counters, fine extensions or small highlights may become visually crowded;
• the visual centre of each side when the train is standing normally.

Repeat this inspection for the reverse side rather than assuming it presents exactly the same compositional problem. The available painting area may feel similar, but printed details can change how individual letters appear. A strong vertical door cue might reinforce the stem of one letter while cutting awkwardly through another. A sequence of windows might work as a rhythm behind wide capitals but interfere with small internal spaces.

Also inspect the top, ends and lower edge as boundaries, even if your main artwork remains on the two broad sides. Extensions that look convincing in a flat sketch can feel cramped when they meet the physical edge of an object. Decide early whether the piece should sit comfortably inside the side panel or appear to push against its boundaries.

Fine layer lines and minor surface variations are normal characteristics of the train’s 3D-printed production. Treat what you see on your specific object as part of the surface you are planning for rather than assuming every area will behave visually like smooth paper.

Choose One Concept or Two Independent Pieces

The first major decision is whether both sides belong to one concept. Make this choice before selecting small details, because it determines what must remain consistent and what can change.

Option 1: Repeat the same piece

Using the same name or word on both sides is useful when you want a controlled comparison. Keep one or two variables fixed—such as letter structure and overall placement—then deliberately change another variable.

For example, side A might use a restrained two-color fill with a clear outline, while side B uses the same basic letters with internal blocks, highlights or a different background relationship. Because the word and scale remain consistent, you can compare how color and detail affect readability.

A repeated piece does not need to be traced or duplicated exactly. Small structural changes often make the exercise more valuable. You might open the counters on the second version, widen the first letter, simplify a difficult connection or adjust the baseline after seeing the first side from display distance.

Option 2: Create related companion pieces

Companion pieces share a visual system without repeating the same artwork. They might use different words in the same handstyle, two related character poses or the same palette with different lettering structures.

To make the relationship clear, repeat at least two elements across the object:

• the same outline color;
• a recurring highlight color;
• similar letter weight;
• matching background shapes;
• the same direction of lean;
• a repeated symbol, character feature or graphic accent.

Two shared elements are usually enough to establish a connection without making the reverse side feel like a copy. If everything changes—word, palette, structure, density and background—the sides will read as independent works instead.

Option 3: Use two contrasting pieces

Contrast can be the concept. One side might be controlled and highly readable; the other might be compressed, abstract or character-driven. One can use broad color fields while the other relies on the monochrome printed base as visible negative space.

Intentional contrast works best when you can state the difference in one sentence before painting: simple versus complex, warm versus cool, lettering versus character or day palette versus night palette. If the distinction cannot be described clearly, the second side may simply look disconnected.

Option 4: Treat the second side as a revision

The reverse can function as a second attempt rather than a companion artwork. Complete side A, review what succeeded and identify one or two specific improvements for side B. This turns the object into a record of development.

A revision might correct crowded spacing, improve the balance between the first and final letters, reduce unnecessary extensions or create stronger separation from the printed train details. Do not change every variable at once if comparison is the goal.

Map Lettering Around Windows, Doors and Printed Details

The printed details are not random obstacles. They establish a visual rhythm that can guide letter placement. The practical question is whether your lettering will sit over, between or in conversation with those details.

Use the details as alignment cues

Vertical printed elements can help establish major letter stems or divisions between letters. Horizontal cues can suggest a baseline, cap height or the level at which a fill changes color. This does not mean every part of the piece must align perfectly with the train design. A few deliberate alignments can make the composition feel grounded while allowing the rest of the lettering to move freely.

Protect important counters and connections

Before painting, note the most vulnerable parts of the word: small counters, tight overlaps and narrow joins. If a printed door edge or dark window area passes through one of those points, the letter may lose clarity.

You have several compositional solutions:

• move the whole word slightly rather than correcting individual letters later;
• widen the affected counter;
• change the overlap order between letters;
• use an outline with enough visual separation from the underlying detail;
• allow the printed feature to remain visible in a larger area of negative space;
• simplify an extension that lands in an already busy section.

Decide what stays visible

Trying to preserve every printed line can fragment the piece. Covering every detail can remove the specific visual character of the base. Choose a hierarchy instead.

For example, you may decide that the main window rhythm should remain readable while smaller panel information can sit beneath the composition. Alternatively, you may let the piece dominate the centre and preserve more of the original design around its perimeter. The important point is to make that decision across the whole side, not detail by detail while painting.

Plan for the object, not an imagined full-size train

This is an urban art object and practice surface, not a functional or scale-accurate model. Compose for the physical item in front of you. Very small features that look convincing in an enlarged digital sketch may become visually weak or crowded at the object’s actual size. Prioritise clear letter masses, readable overlaps and a deliberate balance of painted and unpainted space.

Plan Color Relationships Across the Front and Reverse

The sides do not need identical colors, but they benefit from a planned relationship. Start by assigning each color a job rather than selecting a long list of attractive markers.

A practical palette plan may include:

• fill color or colors for the main letter mass;
• outline color to define the silhouette;
• shadow or depth color if the structure requires it;
• accent color for highlights, cuts or small graphic elements;
• original monochrome surface used intentionally as negative space.

The Stockholm train’s reduced black, grey and white design can function as part of the palette. You do not need to cover every available area for the side to feel complete. Leaving selected sections unpainted can separate color groups and retain a visual connection to the object underneath.

There are three straightforward ways to connect the palettes:

Be careful with equal emphasis. If every letter, background shape and small mark uses a different strong color, the printed details and lettering may compete at the same level. A limited hierarchy usually reads more clearly from the intended display distance.

Decide Whether to Paint Both Sides or Preserve One Side

Both sides are paintable, but painting both is an option rather than an obligation. Leaving one side in its original monochrome design can be a complete curatorial choice.

Preserving one side may make sense when:

• you want a clear before-and-after comparison on one object;
• you value the supplied Stockholm-inspired design as part of the display;
• you want to complete the second side later with a more developed idea;
• the object will be positioned so one particular side is normally visible;
• you want the painted side to function as a single focal artwork.

Painting both sides may be more useful when you are comparing styles, building a paired concept or using the object as a compact record of two studies.

If you are undecided, do not fill the reverse merely to make the object feel finished. Complete one side, place the train on its stand and live with the result for a while. The second side can remain a future decision. An intentionally untouched surface is stronger than an unplanned composition added only because space was available.

Build a Simple Before-Painting Layout

Yes, sketching before using acrylic paint markers is worthwhile. The sketch does not need to be a finished illustration. Its purpose is to settle scale, rhythm and hierarchy before the permanent visual decisions begin to accumulate on the object.

A practical planning sequence is:

1. Choose the role of each side. Label them side A and side B, then write one sentence describing each composition.
2. Draw two simple side-shaped boxes on paper. Mark the approximate positions of the most visually important printed details.
3. Block the total letter mass. Use one broad shape before drawing individual letters. Check whether the composition is centred, forward-weighted or intentionally pushed toward one end.
4. Divide the mass into letters. Establish widths and spacing. Do not add effects yet.
5. Mark critical overlaps and counters. Compare them with the positions of windows, doors and other printed information.
6. Assign color roles. Note fill, outline, depth and accent colors rather than fully rendering the sketch.
7. Reserve negative space. Mark which areas of the original monochrome design should remain visible.
8. Reduce unnecessary details. Remove small additions that do not improve structure, movement or readability.
9. Compare both plans together. Confirm whether their similarity or contrast is intentional.

If you plan digitally, keep in mind that a flat image cannot fully represent the train’s physical edges or normal viewing angle. Use the digital layout as a map, then compare it with the actual object before painting.

It is also useful to establish a stopping point in advance. Decide what constitutes a complete side: perhaps fill, outline and one accent system. This reduces the temptation to continue adding details after the main composition is already working.

Review Each Side from Its Display Position

Close inspection is necessary while working, but it is not the only useful viewpoint. The included platform-style stand lets you evaluate the object as it will be displayed on a desk, shelf, studio surface or in a collection.

At several points, place the train on the stand and review:

• whether the first and last letters carry similar visual weight;
• whether the composition appears level or unintentionally tilted;
• whether a central detail divides the word awkwardly;
• whether small accents remain visible from the likely viewing distance;
• whether enough of the underlying train design remains legible for your concept;
• whether side A and side B feel like the relationship you planned.

Turn the train around rather than judging the reverse upside down or from an improvised angle. Each side should be assessed in its normal upright display position. A letter connection that seems balanced while the object is held close may dominate once it is standing.

Also compare the silhouettes of the two compositions. Even though they are viewed separately, a similar overall footprint can connect very different pieces. Conversely, a major change in scale can reinforce a deliberate contrast. What matters is that the difference looks chosen.

Photograph and Document the Finished Train

Documentation is especially useful for a two-sided object because one photograph rarely explains the complete project. Record the train before painting, during the main stages and after both sides have reached their intended state.

A useful documentation set includes:

• side A before painting;
• side B before painting;
• the initial composition sketch or layout notes;
• side A after the main fill and structure are established;
• side B at the equivalent stage;
• the finished side A in its upright display position;
• the finished side B from a comparable angle and distance;
• an angled view showing that both designs belong to one physical object;
• a final view of the train on the included stand.

Use comparable framing for the straight side views. If one photograph is close and dramatic while the other is distant and angled, it becomes difficult to compare composition, spacing and color balance.

Keep a brief written record as well. Note the concept, palette roles, what you intended to test and what you would change in another version. Useful observations are specific: the final letter needs more width is more actionable than the piece feels off. Likewise, the shared outline connected the two sides tells you more than simply recording that the colors worked.

If one side remains unpainted, document that choice rather than treating it as an unfinished omission. Photographing the painted and original sides under similar conditions makes the comparison clear.

Stockholm Practice Train Specifications and Included Parts

The Stockholm Graffiti Practice Train is City Series 11 in the CHROMATICA City Series. It is an independent urban art object inspired by Stockholm graffiti, metro and urban culture.

• Product: Graffiti Practice Train / Urban Art Object
• City: Stockholm
• Series: CHROMATICA City Series
• Series number: 11
• Approximate size: 20 × 10 cm
• Production: 3D printed with direct UV-printed details
• Painting surfaces: Front and reverse side
• Designed for use with: Acrylic paint markers
• Included: One Stockholm Graffiti Practice Train and one platform-style display stand

Acrylic paint markers and decorative accessories are not included. The object can also be kept in its original monochrome state and displayed without painting.

The Stockholm design contains no official operator logos, route numbers, destination displays or line identifiers. It is not affiliated with, licensed by or endorsed by any railway operator or transport association.

The strongest two-sided plan is not necessarily the most complicated one. Decide what each surface is meant to teach or communicate, account for the printed details, give every color a role and review the work from its real display position. Whether you create a matched pair, two opposing styles or one painted side beside the original design, the result should make sense when each side is viewed alone—and when the train is understood as one complete object.
