Save space in your wallet & organize all your gift & store rebate cards by putting a hole punch through them and adding them to a key ring. There are also "frequent user" card wallets available if the key ring is too much.
Ayla would love to have one of these for her crayons/ colored pencils/ markers. I'm thinking with colored cups that she can paint herself :) Use a wine rack and large cups to store markers, colored pencils. for paint markers and such.
