I could never get my pounce pad to actually "work". On a quilting show was Marilyn Badger and she uses the Pounce chalk but with a sponge brush instead of the pad. She put the chalk in a bowl, dipped the DRY sponge brush and brushed it over her stencil. That method works very well for me!
The sponge brushes you can get at Wal-Mart in the paint section. You can get a large bag of them for a small price. GREAT!
