These are for the CAS challenge to use brads or eyelets. I DID NOT invent this fun spider/brad dealie-o, but I did fall in love with it and use it! My cards are "postcards" - 2 3/4" x 4", and the bases are all cut from a single sheet of Making Memories dp that had the shapes already there, saving time and effort (part of the CAS charm). These were way too much fun! Thanks for looking!
