I primarily use "craft paints" . . . you know, the inexpensive ones that come in 2 fl oz (59 ml) plastic bottles. They are usually found in "craft stores" or "dollar-type stores".
Anyway some years ago I purchased a "Provo Craft Spinner Rack". It holds 160 bottles of these 2 oz craft paints. I have found it quite useful for easy view and use of these paints.
Still I had never come close to filling it until this week when my dear wife gave me her collection of craft paints (her "numb hands" prevent her from controlling her brushes) . . . which also explains some of the colors that don't seem very martial.
As you can see from the above photo of the "warm side" of the rack, each side holds 80 paints. (Hopefully if you click on it, you'll get to see a larger image; but Blogger keeps changing the way it acts when you do so . . . so who knows.)
The image below will show you the "cool side" which also contains the varnishes and metallics on the right hand side.
I got my on eBay . . . but you if you want to get one that way you need to take your time. Some folks want outrageous prices for them and others are quite reasonable. I think that I got mine some years back for around $30 plus shipping . . . but check out the cost of shipping before you bid on one . . . again sometimes that cost is unacceptable.
I would suggest that you check with any local craft shops first to see if they carry them . . . or how much they'd charge if you ordered one.
Below is an image of the side of the rack . . . so you can see the central post that the whole thing turns on. By the way, when full of paints like this it is quite heavy.
Finally you will have noticed that I've painted each lid the color of the paint inside. This is because paints can dry either lighter or darker than their "wet" appearance . . . and it makes it very easy to find the shade of color that I want.
By the way, while most come with white lids, some craft paints come with a "gold top" (such as the fourth ones down in the photo above). These I first paint white before painting their proper color on them.
