The four-letter system that finds a battery by feel

An open drawer, printed flat across the chest in black and amber. Four wooden dividers split it into four lanes. A small card sits at the head of each one, reading AA, AAA, C, D — one card per lane, left to right. Each lane holds batteries of exactly the size its card names, lying on their side in a row.

Nobody re-sorts this drawer. It never needs it. Everything already has a lane.

Why sort a battery drawer by size instead of by brand or by charge?

Because size is the one thing about a battery that's fixed and impossible to get wrong, and brand and charge are neither.

A battery's size never changes and never has to be checked — it's built into the object. Sorting by brand groups things that behave identically anyway; sorting by charge would require testing every battery on a schedule nobody keeps. Size sorts once and stays sorted, which is the entire reason a system like this survives years without being redone.

What makes a lane system like this actually work, day to day?

That the label matches something you can find without reading it — the width of the lane itself.

The AA lane is narrower than the D lane before you've read either card. In a dim room, at a rushed moment, a hand can find the right lane by feel and only glance at the card to confirm it. That's a close cousin of a shed's tool silhouettes showing a gap from the doorway before anyone's counted anything — the system is doing work before anyone consciously reads it.

Do I need permission to print a system like this on a shirt?

No — a drawer, four dividers and four handwritten cards reading AA, AAA, C and D describe a way of organising, not a design anyone owns. There's no brand's product here, only the standard size names that already belong to no one.

Where a licence would actually apply

Only if the artwork copied a specific manufacturer's own battery packaging or printed branding — that belongs to them. An invented drawer with plain hand-lettered cards, like this one, needs nobody's sign-off. Style has no owner. A work does.

Does this size-first sorting logic apply to anything besides batteries?

Screws, fuses, nails, anything that comes in a small range of fixed physical sizes takes the same lane system for the same reason — sort by the dimension that never changes and the sorting never goes stale. It's a different discipline from a freezer bag's shorthand, which is sorted by date rather than size — there, the thing that matters is what you can't see at a glance; here, it's what you can.

Isn't a whole drawer with dividers overkill for something you could just keep in a bag?

A bag holds batteries; it doesn't answer "which size, right now, without tipping it out." The dividers are the entire difference between storage and a system you can use without looking twice. Once the lanes exist, keeping them sorted costs nothing — a battery only ever goes back into the lane it came from.

Does it print well?

Yes — the drawer's straight dividers and the flat handwritten cards are hard-edged shapes that hold up cleanly at fabric scale in two inks.

Black carries the drawer's structure and the battery outlines; amber sits inside just the label cards and the battery ends, so the eye lands on the four words first. Keep the card lettering blocky rather than fine-lined — thin serifs on AAA in particular are the first thing to fill in on cloth.

How do I get one made?

Describe the drawer at JustOG — how many lanes, what's written on the cards, which sizes get kept. 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.

Four lanes, four cards, and a hand that already knows which one it wants before it looks.
