For anyone who is a member over at QNN, look for the first video in the Linda Taylor 100 series, Linda's Longarm Quilting. She has Pam Clarke as a guest, using the Pounce - a great visual (and great design ideas as well!)
Once I saw to rub it instead of 'pounce' it (really, they should reconsider the name LOL!) it works great for me and stays very well. I use it and the Designs with Lines stencil to mark the centers of my blocks for painting them too - works great and irons right off :D
