Yep, Steve that is right, make sure your paint is still wet. I actually have the paint in one hand, and embossing powder in the other, and as soon as the paint is applied, I dump a lot of the powder on and forget about it for at least a couple hours. After that, just tip your floor over and give it a little tap, and you get a perfectly smooth carpet.
I'll never use flocking again, in fact, I've got several different colors that I'll probably toss out unless somebody wants it.
