The challenge is "anything goes"! Just use a stamp that you have one year or older, and make your creation in this theme. Here is a copy of the challenge graphic and the card I created for the challenge. I'd love to see what you make, so come join the fun! And check out the cards that have already been submitted to the challenge, they are really awesome!
And, be SURE to stop back by the Retro Rubber Challenge Blog this coming Sunday, to learn who the winners are of this current challenge! Best of luck everyone and thanks for playing!
