I've never heard of them!!! I clicked on the link provided by Wednesday Stamper and saw these and decided to give it a whirl! Here's my MOO cards - they are quite addictive, and now that they've been photographed I'm going to punch a hole through the lot and keep them on a clip ring and just add to them from time to time. I must admit I had more fun with these than I ever did with inchies!
Thanks for looking!!
