In the comments on the last post Jeanie said
"I've got a Spellbinders Wizard (love the product & love the company) so I decided to try cutting plain fabric. I tried batik, "cheap" (i.e. low thread count) cotton, muslin & flannel. Everything I tried cut very cleanly. Not one thread was left hanging!"
I'm not surprised at this, as the Wizard is a more heavy duty die cut machine than the Cuttlebug. I want to emphasize that my results were just for the Cuttlebug, and I'm glad Jeanie mentioned her results as it might help someone else who could be looking for a die cut machine specifically to use with fabric. Thanks, Jeanie!
