I am in love with this super cool never ending card idea and have so far made two designs, both Halloween. It is just super cool and fun. Check out the video of one that I made using Stampin' Up's Frightful Sight DS paper and some of their latest stamps. I used three sets to design this card . . . Out on the Limb, Gift Givers and Wicked Cool.
I've got some thoughts in the works to do a few birthday designs as well! Get ready.
