I am a fan of Heat & Stick powder, although I know a lot of stampers who just do not like it at all. It allows you to glitter a complete image if you like, with great adhesion. I used heat & stick to do the "Hey!" image on this card:
Gallery at Splitcoaststampers
I stamped the Hey with Classic ink, then stamped right on top of the turquoise image with VersaMark
(used my Stamp-a-ma-jig here), poured on Heat & Stick, dumped off the excess, & heated carefully with my embossing tool. As soon as it changed from white to clear, I poured on Dazzling Diamonds. You can heat set for a couple of seconds, and the glitter is well applied. It's one of those things that you just have to play with a little!
Have fun if you try!
