No Holes, No Landlord: Building a Paint Store from Sweet Tubs and Shortbread Tins

There is a particular kind of hobby clutter that only appears once you own more paint than shelf. It starts innocently: a few dropper bottles, a couple of Tamiya pots, one heroic tin of varnish. Then a birthday brings a Quality Street tub, Christmas adds a shortbread tin, and suddenly your paints are living in three different boxes under the bed. If you rent, the obvious solution — a wall-mounted rack — comes with a landlord-shaped problem. Nobody wants to explain six rawl plugs to a letting agent.

The good news is that UK biscuit tins, sweet tubs and sturdy shoebox lids are almost purpose-built for this job. They are free, they stack, they slide under furniture, and they can be rearranged without a drill bit in sight. The trick is to stop treating them as random containers and start treating them as a modular system.

Start with the tins you already have

Before buying anything, raid the kitchen cupboard. A classic rectangular biscuit tin is excellent for standing dropper bottles upright. Round sweet tubs are surprisingly good for wider jars and weathering powders, though they waste a little space at the corners. Shallow shoebox lids make decent trays for the bottles currently in use, and a sturdy cardboard box can become the overspill store for duplicates and backup pots.

Give each container a quick clean and make sure it is properly dry. Sugar crumbs and paint bottles are not a good mix, and any residual moisture will do your labels no favours. If a tin has a dent or a rusty seam, keep it for tools rather than paints — rust and acrylics are not friends.

The aim is not a beautiful display cabinet. It is a working store that survives being moved, shuffled and shoved under a desk. Function first, aesthetics second.

Foam is the quiet hero

A tin full of loose paint bottles is a rattle waiting to happen. A sheet of craft foam, sometimes sold as EVA foam, transforms the inside of a biscuit tin into something much more civilised. Cut a base layer to fit the bottom, then add dividers or a second layer with holes cut for bottle bases. You do not need precision engineering. A craft knife, a steel rule and a bit of patience will do.

Foam also gives you a little grip, so bottles stay upright when the tin is carried. If you use an airbrush, this matters. A toppled bottle of thinned paint can leak through a cap and turn the inside of a lovely shortbread tin into a sticky mess. A foam insert costs a couple of pounds and saves a Saturday morning.

For odd-shaped bottles, cut slots rather than circles. Slots are more forgiving, and they let you squeeze in one more pot when the collection inevitably grows.

Label windows and the two-second glance

A paint rack only works if you can find things. Stick a strip of masking tape on the front of each tin and write the contents on it. Better still, cut a small window in the side of the tin and slide in a paper label. That way you can change the label without peeling off tape and leaving a sticky ghost behind.

The label should describe the job, not just the brand. “Vallejo” is not useful when you are looking for a specific green. “German armour greens” or “rust and chipping” tells you far more at a glance. If you have a label maker, great. If not, a black marker and a steady hand are perfectly acceptable.

Keep the labels facing the same way when the tins go back on the shelf. It sounds fussy, but it turns a pile of boxes into a system. You will thank yourself at 9pm when you are trying to finish a base coat.

Sort by project, not by brand

Most of us start by grouping paints by manufacturer. It feels tidy, but it is not how we actually work. A project usually pulls from several ranges: a primer, a base colour, a wash, a metallic, a varnish. If those live in four different tins, you spend half the evening hunting.

Try sorting by project instead. One tin for the current army or model, one for scenery and terrain, one for metallics and effects, one for the “someday” projects. Within each tin, keep the most-used bottles at the front. The back row is where paints go to be forgotten, so treat it as long-term storage rather than everyday stock.

This approach also makes packing for a club night or a friend's kitchen table much easier. Grab the project tin, add a brush roll, and you are done. No digging through the whole collection for one pot of bone white.

Humidity control in a small flat

UK flats are not famous for stable humidity. Bathrooms steam up, kitchens get damp, and windowsills can be surprisingly cruel. Paint tins are not airtight, so it is worth adding a small silica gel sachet to each container. The kind that comes free with shoes or electronics is fine. Recharge them on a radiator now and then, or swap them out when they stop doing their job.

Do not overpack the tins. A little air movement around the bottles helps, and it makes it easier to see what you have. If you store paints under a bed or against an outside wall, check them every few months for condensation or rusty caps. A quick wipe-down is cheaper than replacing a dried-out pot.

Rotation and the back-row problem

Every paint collection has a back row: the colours you bought for one project and never touched again. The fix is simple. Once a month, pull the back row forward. Use the paints you have, or at least check they are still usable. A toothpick stir and a drop of thinner can rescue a lot of acrylics, but only if you catch them before they turn solid.

A small mark on the cap — a dot of paint, a sticker, a scratch — can track how recently a bottle was used. It is not a perfect system, but it makes the mystery bottles visible. If something has not been opened in a year, ask yourself whether it earns its space. Charity shops and club swap meets are good homes for duplicate pots.

Build a tier system that survives moving

Stacking tins directly on top of each other is fine until you need the bottom one. A simple tier system solves this. Use shoebox lids as shallow trays, or cut foam blocks to create steps inside a larger box. The goal is to see every label without unstacking the whole pile.

When moving house, the tins become their own packing boxes. Tape the lids shut, add a strip of tape across the label window, and carry them separately from heavy tools. It is a much kinder fate than a carrier bag full of loose bottles rolling around in the boot.

The five-quid finishing touches

A few cheap additions make the system feel deliberate: a roll of masking tape for labels, a pack of foam sheets, a handful of silica sachets, and a permanent marker. That is about it. You do not need a 3D printer, a wall bracket or a landlord conversation.

The biscuit tin paint rack is not glamorous. It is a practical answer to a common hobby problem, built from things that were already in the cupboard. And when the collection outgrows it, you can rearrange the tins, add another sweet tub, and carry on without leaving a single hole in the wall.
