This is a repost from something I just shared in response to someone's question about cutting fabric.
The primary reason I originally purchased my SB a year ago, was to be able to cut fabric. In the time between, I've done about a bajillion heat-transfer vinyl designs on tee shirts for my husband and gkids, as well as cardstock cuts for school displays.
I finally decided to gather my courage to cut cotton fabric for an appliqued picture of my mother.
After a bit of trial and error, I just had GREAT success cutting the fabric!!!
V = 185, F = 60, Blade = 30 Fabric and 45 Detail
I got equally good results with the 30 (fabric) blade in the Click Blade Holder at setting 5, as I did with the 45 detail blade in the detail holder.
The secret to success (drum roll), was as others have shared...starch. I super starched the fabric. I just used a typical spray starch with an iron, redoing it about 4 times (until it was stiff)
Then, I backed it with Steam a Seam 2, but ironed until it was bonded to the fabric.
Bottom line, in addition to the correct bade setting (I had to fiddle with the height), from my experience I'm going to make sure my fabric is well stiffened with something that washes out. And, I'll make sure my fusing product has really adhered to the fabric I'm cutting.
In early, disastrous attempts, the fabric would lift from fusing and was so pliable, the wheels could drag on it.
Good luck!
