I few months ago I finally replaced my brown bookshelf with Jetmax cubes, which hold way more than the shelf did (and take up less space). This is how I use them:
-The bottom 6 cubes on the left are where I keep my scraps, sorted by colour (I've done this for awhile now and I used way more of my scraps now)
-Some of the other drawers hold cards, unfinished card blanks, scissors and tools, kits I've made up or purchased for special projects
-one of the larger drawers has dividers in it and holds my flowers sorted by colour (I there's a pic in my gallery) and the other large one holds my jewelry making supplies. -then (obviously) paper on the open shelves. And some canvases for painting.
