Before you head off, I wanted to show how I used the Quick Coloring technique. I began by stamping the balloon with Saddle pigment ink and then let it dry completely. I created two different masks: first of the outline of the balloon so that I could sponge then blue background. Then I stamped the image again on copy paper. I cut out the hot air balloon portion, and then sponged Creme Brulee in those two openings. Finally,I stamped the balloon onto some of the Sorbet and Crystal Blue B&T, cut them out, and paper pieced them onto the balloon. (It sounds a lot harder than it actually was!)
Give this card a try! I think you'll love the results.
