great find!
i saw another fantastic way to store your markers/paint brushes etc. i have a friend whose husband works at a gun store. you can buy little plastic boxes that look like recipe card holders, and then cut of the lid. then they sell inserts that hold bullet cartridges (i know this sounds weird). he bought one that had 5 x 12 holes in it. the holes for the bullets are the perfect size for a marker. they stand up on a table, and there are extra holes for the versamarker, paint brushes, etc.
i know, sounds weird, but oh so cool!
