1. BY USING rhinestones
what are rhinestones?
Well rhinestones are made of glass but in such a way that they give a nice shine so they look like real gems. The front is facetted glass. And the more facets the glass gets, the more shine.
The back of hotfix stones should be mirrored with a silver coating to reflect light, just as mirrors should be coated with silver to reflect reflections. Without the coating, a flat back piece is no more than a piece of transparent glass of any shape that does not reflect light except for the surface.
The back is in a gray, black or green color. If you look closely, you can see that there has already been added glue to the flat surface. Since there is glue on the stones, you only need to apply heat to adhere them to fabric or other materials.
By the way rhinestones are called strass in Belgium and Netherlands as in many other European languages. Both are used interchangeably. There is also a size chart for rhinestones.
