My card, inspired by this photo, is a Triple Stamping card, which is always fun.
I stamped the script on a piece of vanilla cardstock and cut it out with a Mega Curved Rectangle Spellbinders die, then colored on the rainbow using Copic and Prismacolor markers. I had tried using the original directions for the Triple Stamping card but had some difficulties. (There are about three or four tries of this card now residing in my trash can!) After I colored the rainbow, then I cut the two smaller pieces with two other dies from the set -- and matted them with the black, using the the directions from my tutorial.
Hop on over to Speedy TV and check out my challenge. There are two other rainbow photos which may inspire you.
