I used clear acetate for the card base. I haven't made a clear card in a while and I don't think I've ever done one for my class so this should be fun. I used Pure Poppy striped paper for the front and back covers (the front and back have the same red layer on them). Inside I added white card stock to cover the adhesive lines of the red on the outside.
The star is from Star Prints, stamped in Midnight Muse on white cards stock. I used one of the more open stamps so the white shown through the blue. The button is a Enchanted Evening vintage button tied with natural jute.
