I finished this collage today. It's 5" x 5" on masonite board. It's a birthday gift for a very dear friend. I'm also entering it in a collage challenge contest on another blog.
I first gessoed the board and then attached a piece of Tyvek paper I had stamped beforehand. I had a scrap left which I've also scanned. (This is a technique on Mary Jo McGraw's DVD where you ink Tyvek with several colors of dye ink and then overstamp with black permanent. Tyvek is the material that priority envelopes are made of - I recycle envies we receive, but you can also purchase this.)
I scraped on pink and blue acrylic paints with the edge of a credit card, then stamped different designs in Memories black permanent ink. I adhered a butterfly sticker, the image of two girls from the Internet, a crown cut from a page of an old book and two real postage stamps with gel medium. I added three turquoise Stickles dots on the points of the crown.
