When I got mine, I didn't read the directions very well. I thought, "Pounce: Bounce happily." So, I started off by bouncing the thing up and down on top of the stencil and fabric. *Cough* *Cough* *Hack* *Hack* Not very many good markings were left.
Then, I got smart and just rubbed it over the stencil. Perfect markings! I didn't have any trouble with it rubbing off or anything. I ironed it off, and the white came off perfectly.
It's a lot easier that tracing everything. That's for sure!
