Hello Everyone! Today I’m just doing a quick post about how I store my 12 x 12 paper. I use a plastic 12×12 filing box and these thicker plastic envelopes. I purchased both at Hobby Lobby. The 12×12 paper holders come in a 3 pack and are wonderful. They hold all the paper in the middle and the scraps can go in the front and the back. For my solid card stock I have 30 of the pockets and i put 2 colors back to back in each with their cordinating scraps on either side. Thanks for looking!
