I have seen quite a few cards in blogland made using the washi tape from the Epic Day bundle so I had to try one as well.
It has to be one of the quickest and easiest cards ever! Some random stamping with Calypso Coral and Crumb Cake using Confetti stamp set then three strips of washi tape. The sentiment is stamped onto the tape from Bring on the Cake set. It's a good idea to give it a quick blast with a heat gun as the ink takes a little while to dry on the tape.
