To make this necklace, you'll need:
Polymer Clay (any brand will work, I personally prefer Sculpey)
Rubber Alphabet Stamps (I found mine in the dollar section at Michael's)
Large Jump Ring
Grab a small piece of clay and roll it into about a 1" ball. Try to get it as smooth as you can. The ball doesn't have to be perfectly round.
Using something smooth (I used the stamp kit lid), smash the ball down until it's the size and thickness you want. I usually try to get mine to a little less than 1/4" thick. Try not to use your fingers too much or your pendant will be covered in fingerprints.
If it ends up being too big, take off a little bit of clay and start over. If it's too small, add a little clay until it's the right size. After making a few, you'll be able to tell how much you need.
Sometimes the clay can get really sticky and/or too soft if you've been handling it too much. If this happens, just set it aside for a minute to cool down. You want the clay soft, but still firm.
Next, take the stamp and lightly press it into the clay where you want the letter to be. I am not the best at getting it centered, so I usually put it slightly to the right of the center. You can certainly place it wherever you want. Just don't put it near the top.
If you mess up, just roll the clay back into a ball and start over. If you accidentally press the stamp too hard and leave corner marks from the stamp, you can lightly rub the marks and they should smooth back out.
Using a pin or small skewer, carefully poke a hole in the center top of the pendant and kind of swirl it around to smooth it out and make the hole a little bigger. It might seem easier to pick up the pendant and pierce it, but don't! You can leave fingerprints and/or mess up your stamped letter.
Carefully put the pendant onto a pan and bake it according to the polymer clay package directions. Let it cool completely.
With a small, damp paint brush, water down some white acrylic paint. Paint over the stamped letter. Lightly wipe the pendant with a damp paper towel, and the most of the paint should stay in the stamped area and the rest will wipe clean. If you need more, keep repeating until it looks the way you want. You could also use a tiny paint brush, and paint in the letter itself instead. It's not perfect, but I like to think that's part of the charm!!
Once the paint has dried, you can spray the pendant with clear spray paint or polyurethane spray to protect it and give it a little shine. This step is optional, but I like how it looks.
Open a large jump ring and hook it through the hole in the pendant. Close the jump ring.
You can even make these necklaces for kids! The "Z" pendant is one I made for my daughter. All you have to do is make a smaller ball, but the rest of the steps are the same.
Slide the pendant onto a chain and add a lobster clasp and small jump ring to the ends of the chain to finish your necklace. You can also add a bead or two with a headpin and a small jump ring to add a little more flair to your necklace.
