I didn't make a literal rainbow but I did use all the colors.
I took the Big Band Confetti stamp by Winnie and Walter and using a variety of Hero Arts Shadow Inks made this celebratory card. The sentiment is a conglomeration of two stamps by PTI and the sparkle embossed stars are a SSS die.
ETA: Oops, missed the deadline. I don't know when it was. I had written down Saturday, March 1 on my challenge list. Oh, well, at least I have another birthday card for my stash.
Thanks for stopping by. I hope you celebrate each day as if it were your birthday.
