Here's a picture of my crappy set up. The green box holds a Norton hard black Arky, the blue box a No. 1 Washita (both just made from a piece of SYP 2x10 sitting around the shop). My almost 4 year old daughter loves to paint and I needed to box both of those stones. Medium and fine Norton synthetic stones round out the collection and they are a nice sliding fit on the lumberyard pine tray; I don't use them that close to each other.
