^You would also have to work out how to attach it by yourself.

I take off all the tape on my piece, spray a bit of alchohol on my head first...and then wack the piece on. If I'm wearing regularly I can line it up reasonably well the first time, but if I've had it off a few days, I try to do it in sections. But the stylist cut off a bit off the lace by accident, so its too short in one corner..argh, which means I've got to stretch it a bit to get it aligned. But it turns out ok.
