I use my pounce pad all the time, and it comes off, you can use a clean paint brush or a piece of batting and it comes off, there is some that irons off. I haven't tried it as it only comes in white.
Pam Clarke demonstrated a pounce pad at the IMQS showcase in Overland Park. The secret is to make sure you have the rough side of the stencil down and your rub across your stencil not pounce.. When you first fill the container with chalk you need to put it in a plastic bag and beat the pad until the chalk starts coming out of the pad. I did not know all of this and my pouncer layed in a drawer for years. After finding out the correct way to use it, it works fine.. Also you can use a little spray adhesive to hold the stencil in place. Hope this helps, it works for me. Not sure if there is a tut on utube but I will check it out.
