Hi Ava, depending on whether your undrilled stones are flat, rounded or very irregular in shape, my best advice would be to first look at the sample photos of these four choices:
1.For a flat stone, similar to a cabochon, you could use DVD 2 in the Beginner Series, that teaches how to formulate and create a frame to make a pendant;
2. DVD 3 in the Beginner Series not only shows how to make a harness for a puffed heart, but I also talk about how to use this design for other irregular shaped items;
3. Also in the Beginner Series, on DVD 6, you learn how to formulate and create a cage that will fit just about anything!
4. In my Jump Start Series Lesson 3 you can learn how to Lock That Rock! into a charm or pendant that could be used on a necklace, bracelet, cell phone charm or key chain!
Have fun with your rocks!!
