32-Compartment Drawer Organizer -- I bought an item similar to this at B,B & Beyond, and I've loved my sock/bootie drawer ever since. Mine is a glossy nice cardboard, but because of how it's designed it can squish in and out a bit [like an accordion] to accommodate some variety of drawer sizes. Fits my 36" wide x 24" deep x 4.5" high drawer [exterior dimensions]; wouldn't recommend for a tall drawer; lose too much vertical space.
