I like the Pounce if I am using a stencil. If you haven't used a Pounce, the name Pounce is not what you do. You don't pounce the pad you rub it on the stencil. When you first fill the pad you then slam it down on a solid surface about 100 times. Many don't do this so think it doesn't work when they fill it and then nothing happens. The inventor of the Pounce demonstrated it at Paducah show and he slammed it as hard as he could for several minutes. You only have to do this slamming when it's new, then the pad is saturated. It glides over the stencil. I have never had a problem with removing the chalk. It washed or ironed off depending on the color.
When I don't use the chalk I use Crayola Ultra Washasble marker fine tip. It washes out completely.
