This is the refill for our #QPB, Quilt Pounce Pad with Blue Chalk. It’s a great color chalk to use on dark colored fabric as well as light. If you use it on prints that have a lot of blue in them you may consider using our pink chalk instead. There are 4 oz. of chalk in the bag, the same quantity that comes with the Pounce Pad. It is enough to fill your Pounce Pad six or seven times. It will provide hours of transferring stencils, it’s hard to say how many quilts because each quilt can be so different but what we go by is how long it lasts at a show when demo-ing constantly with it. The record is over two shows, that’s well over 60 hours. This chalk does NOT iron off. It’s a wash off/ brush off chalk, depending on your fabric. Although it’s not supposed to stain fabric we can’t test every fabric in existence so it is still a good idea to test before using to be sure. You can wash it off in warm or cold water. If it’s bouncing off which can happen on some long arm machines, or in other situations, try spraying ordinary aerosol hair spray over the just pounced pattern. You should see improvement. It doesn’t make it permanent but it does add to the level of adhesion on stubborn fabrics or when high vibrating machines are being used.
