I used the Doodlebug crushed velvet flock
I ran the piece through the xyron so the top was sticky. I dumped some flock on top -- it is humid here and the stuff really clumps together. Then I used my finger to spread it around . I tried tapping the excess off, but I really need to rub the excess off - -again humidity may be a factor. I tried my quickie glue pen for a small corner that I missed with the xyron -- it didn't work well at all.
Clean up -- it was fascinating really. I just used a piece of computer paper to catch the excess. I dumped it into the jar. When I looked at the paper, it seemed to have a slight coating of flock. I rubbed at it again with my fingers and made a significant pile! Enough to dump back into the jar.
