Out of all the dry glitter applications, sugar glitter has worked the best for me when it comes to sticking. It makes a mess but it does stick well to wet gel. There used to be something called thermoline clear from rutland I think. It was a little thicker than pancake syrup. This is want I printed and left wet on top of the design. I would make a glitter screen on 40m with the design burned on it. I would use on old squeegee back and forth twice to sift the glitter. quarter inch or more off contact. After the cure, air hose. I will never use dry flake again, because of the mess, but when I did, this was the method.
