Purchase a "syringe applicator" and twist on colored "tip". Color tips are selected by size of stone and thickness of glue. The largest is green and then orange, purple, white and pink in that order to smallest. Use larger tips for thicker glues and use smaller tips for thinner glues. Just fill the syringe applicator with glue after removing the plunger. Fill syringe applicator about 1/2 full with glue and press plunger down to release any bubbles. Make sure to place crystals stone side up so you can lift them easily with your "wax stick" in order to place them. Just squeeze glue dots onto your surface (you might want to practice on paper first). Start by applying a glue dot or two. Later you can apply more glue dots as you become proficient. The glue dots should be large enough to glue the stone almost to the edge. Syringe applicators and tips are disposable and cheap to purchase. This method of gluing is used by professionals because it works. It is easy, neat and fast.
