These are actually clear as you can see in one of the closeups. To me these are a bit more sophisticated than common glitter, (not that moose decorations are sophisticated). For size I show a few of them on a fingertip.
For these decorations, I start with plywood, spray paint it white, then brush with modpodge and sprinkle on the glitter (the small ones I actually dip in the glitter). I like that they let the color of the base show through and look forward to experimenting with other base colors.
