Hello Sondra - I do pretty much the same as Fay only I put the pixie dust in a small spoon and roll it. Should give you pretty much the same results. My personal favorite is soft gold pixie dust on light topaz.
Here's a very cool chart (hope Kay doesnt mind if I post this link) showing how all the various pixie dust colors look on several different colors of glass.

Good luck - I know you will get the hang of it quickly.
