Here's my take on the Color Challenge #290 *and* the Ways to Use #290 it Banner theme. I didn't have those SU! colors, but I did my best matching my other inks up against the catty. =)
I used a small, accent image from Waltzing Mouse Stamps' Very Vintage Labels No. 4 to make the banner. I stamped it directly onto my single layer card, then stamped on a separate piece and stuck it on over the base layer with pop dots. The happy birthday image is from PaperWorks Co., illustrated by Rachelle Anne Miller.
