Here are some photos of fabric cuts made by the Groove-E. The lady who has this business has cut the following:
Taffeta
Satin
Silk
Very thin liner fabric (not good for use with the thermo web; too thin so adhesive goes through)
Twill, med weight
Linen (thin)
Brocade (didn't work well)
She is first applying Heat n' Bond to the fabric before cutting, but it's not essential to do that with all fabrics.
Hope this helps!
