This is a really easy, fun card to stick a gift card in. I followed these directions from this blog and this is my version. Inside and out. Try it, its easy :).
If you don't want to take notes from the tutorial, here are the things you need to know:
Your piece of paper should be 4 1/4" x 11. Score at 3", 5.5" and 8". Then fold on the scores. I guess you will have to watch the rest of the tutorial so you know where to glue the flaps and where to use the word window punch and circle punch but it is really quick. I am making more now and they are going together real fast!!!
