These little scrapbook pages fit inside trading cards you can buy at the $ store. I make them up just as you would a scrapbook page, punch a hole through the plastic and the pages. and thread them together with a chain, ribbon, or ring binder clip. I carry them around with me, like a little brag book to show my friends and co-workers what it is that I have been working at and having fun with. They are so quick to make and it is easy to add to the collection.
