This is my fabulous paper bin with adjustable shelves that covers the entire wall!! Three columns hold 12 x 12 paper, one column holds 8 1/2 x 11 (great when you have a whole ream), and the column to the right hold containers which house my scraps. I still need more shelves so I can divide colors a bit more. I store mostly by color but if a manufacturer has a collection, I do keep them all together under the major color. Extra shelves are stored on top.
