I used to have a jewelry keeper that hung on my bathroom door. It was about 12" x 24". Don't remember what the back side was, but the front was heavy weight clear plastic with bias tape at the top of the pockets and around the outer edges. There were rows of pockets made much like a shoe keeper, only about 3" square. Worked great! Oh and it could be rolled up for travel.
I've been using the little organza bags lately, but am thinking about making one like I described above that was destroyed when our house burned in 2000.
