The Hot Tool® works well on a glass surface.

Try this technique: Using a piece of glass as a cutting surface (cut fabric comes off easily), use the heated tool like a pencil and cut the fabric on the design line. If the fabric is light colored or light weight, you may wish to have polyester interfacing layered with the fabric as you cut, the two pieces will be adhered at the hot cut edge. By layering Steam a Seam™ with the fabric, you will provide an instant iron-on adhesive.

With a test sample, determine whether to cut with the right or wrong side up. If you are working on the wrong side, make sure to use a reverse image of the design to be cut.
