4 oz. size of Blue Quilt Pounce Powder. It is enough to fill your Pounce Pad six or seven times. It will provide hours of transferring stencils.
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 it's not possible to test every fabric in existence so you must 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. The cheaper the better! 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.
At Pinhole Quilting we prefer not to use coloured chalk or powder and we absolutely say that you MUST test before you use it on your quilt. We actually only use it ourselves for TRAINING, which is why we don't sell the Blue Pounce, only the refills.
If you do want to use it, the Barely Blue is also great option instead of the Blue.
