I used US Artquest matte finish PPA (perfect paper adhesive) brushing it on to cover the entire surface that I wanted to glitter. You then just pour your glitter on and tap off excess. If it's a large area, it's probably best to do it in sections. My big mistake discovery was not putting on a really good layer of adhesive. Without a heavy coat of glue, the glitter has a tendency to run off leaving a very messy look. I do love all the glitter look! I used a microfine glitter we carry and sell. I really like the microfine as opposed to the larger crystals, but the color choice is limited.
One more little thing, a coating of the PPA over the glitter gives a really nice look, less glittery, but really nice. A coating of crystal lacquer gives a shiny glitter look, neither is necessary however.
So long for now, back to summer fun, it's almost over!
