One practice log survives under a case gone entirely blank
A mustard back print covers a hard instrument case edge to edge in blank stickers, all but one small practice-log sticker with almost nothing written on it either.

A hard case, drawn large across the back, its lid tiled edge to edge with stickers. Stars and circles, dozens deep, every one of them flat plum with no text, no logo and no picture on it. In one corner, a small paper sticker with a ruled grid holds on, most of its squares still empty.
Nobody could tell you where any of the blank ones came from. The grid sticker is the only one that was ever meant to say anything, and it barely does.
What's actually printed on the case?
A dense field of identical, unmarked shapes, and one exception.
The lid is a repeat pattern — stars overlapping circles overlapping stars, all one flat colour, no two the same size, none of them carrying a word. Only the small ruled square in the corner is different in kind rather than just in shape: it's a practice log, printed as an object rather than a pattern, and most of its rows were never filled in.
Why are the stickers left blank?
Because what a sticker collection actually records is that something happened there, not what.
A blank shape still means a stop was made, a show attended, a shop walked into — the specific sticker just isn't the point once the case is this covered. Printing them blank keeps the part that actually reports something visible: a surface can fill up with evidence of motion without any of it turning into practice. The case looks busy. The log next to it says otherwise.
Why does the one grid sticker matter more than the rest?
Because it's the only object on the case that was ever meant to be read rather than just seen.
Every star and circle does its job by being noticed at a glance from across a room. The grid sticker does the opposite job — it rewards someone getting close enough to see that most of its squares are still ruled and empty. That's the entire tension the design holds: dense evidence of travel next to sparse evidence of work, on the same lid, at the same time.
What makes a convincing version of this?
Keeping the shapes ordinary and the case doing the visible ageing.
A case that reads as real has stickers that could have come from anywhere — no invented festival names or shop logos needed, since a blank shape reads as more stickers than any single named one would. The case itself should show wear at its corners and along the latch, the way a chord grid worn pale from being touched more than the ones beside it carries its own history in exactly one place rather than all over.
Do I need to reproduce real sticker designs?
Only if a specific shop's or venue's actual mark is the point, and then it's theirs to license.
A real sticker is somebody's artwork or wordmark, the same as any logo would be. Since the whole design here works by leaving every sticker blank, there's nothing to licence and nothing to reproduce — the case gets its density from shape and repetition, not from anyone else's design.
Does this work for a case that isn't an instrument's?
Any hard case that travels covered in evidence of where it's been.
A camera case, a tool case, a flight case for something else entirely — the format holds as long as the surface accumulates marks faster than the thing inside gets used. What has to change is just the case's silhouette; the blank-shape field and the one small sticker that actually says something both carry over.
Does it print well?
Yes, and the blank stickers are the easy part — it's the grid that needs care.
Flat plum shapes with a hard black outline hold their edges at back-print size with no trouble. The ruled grid is fine detail and the finest lines in it want to be thickened slightly so they don't fill in on the weave, the same floor any fine hairline runs into on fabric. Mustard, ochre or a warm olive garment all let the plum sit forward. Two inks.
How do I get one made?
Describe the case at JustOG — how dense the stickers are, what shapes, and what the one surviving sticker in the corner says, if anything. 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.
Most of the grid is still empty, and the case doesn't have room for one more sticker anyway.
