# Tracing paper follows a line, it doesn't copy it > A lightbox glows under two sheets — a flat reference silhouette below, a looser pencil outline on tracing paper above, following the shape but not repeating it line for line. August 22, 2026 · https://justog.club/stories/tracing-a-reference-on-the-lightbox A lightbox glows from underneath two stacked sheets, printed large across the back. The lower one holds a flat, printed rose reduced to a silhouette. The upper sheet is thinner, laid slightly askew, carrying a new pencil outline of the same rose — looser, a little bigger, not sitting exactly over the shape beneath it. A pencil rests diagonally across one corner, just set down. The two roses are related. They're not the same drawing. ## What's actually happening on this lightbox? A reference is being redrawn by hand, not copied by tracing every line exactly. The light from below makes the printed shape underneath visible through the paper on top, which is what a lightbox is for — it's a working aid, the same as a grid or a proportion guide, not a shortcut that removes the drawing from the process. ## Why does the new outline sit slightly askew from the one beneath it? Because the paper on top was never meant to sit flush, and the drawing on it was never meant to be identical either. A sheet laid at a slight angle is easier to check against the original without the two overlapping edge to edge, and it also shows, visibly, that this is two separate objects rather than one artwork with a copy stapled behind it. The offset is doing real work: it's the shirt's own way of showing that a second, independent drawing exists. ## What's the actual difference between tracing and copying? A reference gets followed. It doesn't get reproduced. Using a shape underneath as a guide for proportion, weight and placement is a normal, longstanding part of how a new drawing gets built — the hand still makes every decision about line weight, where to simplify, where to add. What the sheet on top ends up with is looser and slightly larger than what's underneath specifically because it's a new drawing responding to a reference, not a transcription of it. ## Is tracing someone else's reference allowed? If the reference itself is a specific published drawing or photograph, permission for that source image is part of the job — same as any other artwork somebody else made. A generic subject like a rose belongs to nobody; a particular artist's or photographer's specific rendering of one does, and studios and photographers license reference use all the time. What isn't owned is the pose, the subject or the general shape — those move freely between drawings the way [the same swallow shape has for a century](/stories/old-school-swallow-pair). What is owned is one person's particular version of it, which is exactly why the sheet on top here is drawn loose enough to be its own. ## Does this work with a reference other than a rose? Yes — any subject drawn from a flat source works the same way: a skull, a ship, a portrait, a hand of cards. The lightbox and the two sheets are the actual subject of this print, not the rose specifically. Swap the reference and the same relationship holds: one flat shape underneath, one looser drawing responding to it on top, offset enough to read as two separate things. ## Doesn't tracing mean the artist didn't really draw it? Only if the top sheet matched the bottom one exactly, and here it doesn't. A guide used for proportion and placement is a tool, the same as a stencil is a tool once the needle's moved past it — [the ink itself is what makes the final decisions permanent](/stories/outline-first-colour-later), not the reference that got it started. The loose, offset line on top is the evidence of a hand doing that work, not a straight-edge copy of what's glowing underneath. ## Does it print well? Yes, in two inks on the warm grey shirt — dense black for the flat silhouette below, pale amber for the glow of the lightbox and the pencil line above it. The backlit glow is the part to watch: reproduced as a soft gradient it goes flat and grey on fabric, so it's rendered instead as a hard-edged pale field bleeding out from beneath both sheets, which reads as light at a glance without needing a true gradient to sell it — [the same restraint a short palette is built to reward](/stories/why-the-palette-is-small). The pencil line on top stays a single weight throughout rather than tapering, which is what keeps it visible against the glow behind it. ## How do I get one made? Describe the reference at [JustOG](/) — the subject, and how loose the new line on top should sit against it. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped. Designs other people have published are in the [shop](/shop). The pencil hasn't moved yet. The line underneath it already has somewhere to go.
