I love unique necklaces and I find the most unique of necklaces are the ones you make yourself. They are extra special because they are personal to you. I used an owl because I'm slightly owl obsessive :) What will you use?
The first thing you have to do is shape your clay because it is the main piece of your pendant. I did mine in a rectangular shape but you can really do any shape you want. Make sure it's not so thin that it won't be stable and don't make it so thick that it becomes heavy.
(The clay I used was just basic, air-dry modeling clay. I'm sure any type of clay will work just fine for this. You must keep in mind that clay shrinks when it drys.)
The metal hook is the most complicated part of the pendant because it must be shaped and inserted into the clay before the clay has time to dry. Using wire cutters, cut a small piece of wire and shape it into a "U". Now so that the hook doesn't just slip out when the clay dries, you must put two smaller bends in the ends of the "U" going outwards. After you have done this, press the hook into the clay and clean up around it so that the clay is smooth. Leave clay to dry.
Print out the image you want for your pendant, cut it out, and glue it onto the now dry clay. Cut off any hang over edges.
Cut the needed length of ribbon to go around the outside edges of the pendant and cover up the clay. I added a bow to give it a slightly more girlish feel.
(I didn't put it as a step but I also painted the back of the pendant gold to match the owls feathers and cover up the clay. I would suggest painting the back of yours a color that compliments your photo.)
