I also have this smaller cabinet that holds BOM's, kits, and a few WIP. If you look on the bottom shelf, those flatter style boxes are actually scrapbook boxes from Michael's, but they are perfect for 12" blocks and other WIP.
I also wanted to show you my new little design wall! I got the idea from my friend Shari. It's made from a foam board from Office Max (about $15). It's 36"x48" when fully opened. Here I've left it folded, so it's 24"x36". I've covered it with white flannel. I bought a big enough piece to cover the board if I ever want to open it to the full size. Right now, this size is just enough and it's portable and can be tucked away when not in use. You can see the Quilt Inspector is checking it out, too. I think he approves.
