Here's a quick and easy jewelry project to make for Valentine's Day. I found a clear plastic heart-shaped pendant at a bead store (similar ones can be found at craft stores).
Then I cut a heart shape to size out of zebra-patterned tissue paper. Extra-sharp scissors should be used for the cleanest cut. Next I covered one side of the heart with Mod Podge decoupage glue, using a small sponge paint brush, and laid the tissue on it, face down. This is the underside of the pendant; the front side of the tissue will show through the other side of the heart. You may have to work with the tissue a little while the glue is wet in order to remove any creases and air bubbles. I used a straight pin to gently work a hole into the tissue paper to correspond with the hole in the pendant. Finally, I covered the back side of the tissue with another coat of Mod Podge and let it dry.
After the glue dried, I put a red leather cord through the pendant and tied it to make a necklace. Make a Valentine for yourself while waiting for one from that special someone!
