The World's Best Fabric Pounce Chalk
Marking with pounce chalk has just become easier, cleaner, and highly visible
When testing, if the iron is not hot enough, or you do not have batting under the fabric, the chalk may leave a shadow line. If the iron is hot and batting in place and the shadows remain, do not use the chalk on this fabric. The fabric is either not 100% cotton or the chemicals in the finishing process of the fabric are binding with the chalk creating the shadows.
Do not use product with cotton sateen.
Remember to test any and all marking products to avoid disappointments.
