I tried "Aleene's Stiffen Quik", but instead of spraying, I poured some into a small flat container and soaked the snowflakes in it. Then I blotted them with a paper towel and dried them on waxed paper. They are not as stiff as with the sugar starch, but stiff enough to hold shape, and the sheen of the thread is not obscured.
