My local Jo Ann Fabrics doesn't have the Silicon sheets recommended in the tutorial I found for making bias tape celtic knots, would heat safe mylar work? I'm not using my big iron, but rather my small Clover iron I use for applique. Just curious if #1 the adhesive will remove when I go to transfer the design, and #2 if it's too much heat.

Thanks for any help!
