The Paper Arts site talks about everything related to paper including stationery, scrapbooking, and DIY paper projects.

I saw these diecut paper stacks on Joann the other day, these are called “Pocket Full of Posies” and are meant for scrapbookers who want a little sparkle on their pages. These smaller Mat Stacks measure about 4.5 x 6.4 inches and can be used for anything from paper crafting to creating photo mats. They differ in size quite a bit from the usual 12×12 sheets. There are 72 sheets of vivid and colorful paper included here for your scrapbook needs.
