We tried this on quilting cotton, and were *amazed*. Now we all want to make napkins, because this fabric folding pen would make it so easy.

To use the pen, you fill it with the water and four drops of the marking solution and then draw a line on your fabric with it- either up against a ruler or free hand. Then you fold where you drew the line and crease it with your fingertips, and voila- it stays folded! Great for English paper piecing, applique, and general sewing.

Not suitable for impermeable fabrics such as polyester or spot sensitive fabrics.
