Lady Ragnely's Momma made some decoupage jewelry back in the 70's using wrapping paper, a tablespoon or teaspoon of plaster of Paris and crackling or clear acrylic paint. The one on the right has a small safety pin embedded in the back and the one on the right has a hole drilled for a jump ring. We recently discovered Momma still has some of the original wrapping paper! These are from Holly Hobbie and Betsey Clark Hallmark wrapping paper.
@Overstock - The swirl design of this pretty brooch ends in a flower design, all set with fiery round-cut clear cubic zirconia stones. The pin is crafted of platinum over sterling silver and secures with a safety lock.http://www.overstock.com/Jewelry-Watches/Sterling-Silver-Clear-Cubic-Zirconia-Swirl-Brooch/5285236/product.html?CID=214117 $44.49
