Due to migraines I haven't finished my AT-ST, but yesterday I did find a solution to my paint storage. I had been looking for something to show the paints, while keeping them easy to access and that looked good. I originally thought I would go for a large spice rack or something like that.
Instead I found these shelves.
Three of these would hold the entire Citadel paint range (just) and the grey bases are very grippy and mean the pots are very secure. Before yesterday I just had a growing sprawl of pots over my painting area, now I feel like I not only have organisation, but room to grow. And the OCD part of me thinks the paints in a row look pretty.
Of course now I just need to avoid buying paints I don't need just to fill colour gaps.
