Create a necklace with linked or strung beads, or simply use a pre-made chain.
Directions for basic smooth pendants:
Find a constellation that you like.
Take a small black Sharpie and eyeball where the dots need to be placed on the pendant. (If you mess up, take a wet wipe and wipe the marker off. Start over.)
If using the automatic punch, place the pendant on a metal block. Place punch over one of the marks, click down once. For a deeper hole click down twice.
If using the regular center punch, place the pendant on a metal block. Place the punch over one of the marks, and using a brass hammer, hammer down. Be careful as these are sharper and can be punched all the way through the metal!
Repeat until all marks are punched.
Pick out the smallest crystal chatons from your chosen color. Add a little glue in the hole, and place -- with small tweezers -- a small chaton. (Do one hole at a time as the glue dries really fast.)
Repeat until all stones are in!
Make a necklace or use a jump ring and a premade chain to hang your pendant. (In our examples, we antiqued the sterling Satellite chain with Novacan, and buffed the beads out to bring the sparkle back.) For best way to open and close jump rings, see Jump Ring Hint in Jewelry Basics 101 (PDF)
To make a necklace:
Using 24-gauge wire, create and connect a series of beaded simple loops or wire wrapped loops (see Instructions for both in a href="http://www.rings-things.com/Designer%20Tip%20Sheets/jewelry_instructions.pdf" target="_blank">Jewelry Basics 101 PDF). Make the necklace long enough to go over your head, or use jump rings to add your favorite clasp.
