When you buy your supplies, be sure you get a few applicators. Applicators consist of a piece of wax at the end of a toothpick but are absolutely essential. I use GemTac glue and it is flexible and dries clear. Because it dries clear you can use plenty of it. Dab the glue on the spot where you are going to lay the stone. Do the glue and stones one at a time and dab on a drop of glue about the same size as the stone you are going to lay on top of it. Use the applicator to apply the stones and simply touch the wax on the stone to pick it up and touch the back side of the stone to the glue and the stone will come off the applicator. Let your project dry and you are done!
