Flocking is loose fuzzy stuff, I can find it in the crafts section of my Michael's, usually, it's great to make bunny's tails.
It's kinda clumpy, when you sprinkle it on the heat & stick powder, then you press it in, then shake off the excess. Or you can use liquid glue with it. It would be neat if SU! carried it seasonally like they did with the white applique last year (for snow).
I take it you have not yet flocked. A flocking virgin! LOL
Sorry, every time we ladies get around flock, the bad jokes fly.
