Why is paper stabilizer used on cotton fabric for embroidering? I used the fabric spray stabilizer and it worked great. No puckers and the design is soft not stiff. I'm new at machine embroidery and those in my sewing group said I had to use the paper. When I asked why they said that was the way the classes they take say to do it. They have never used the spray. There are many different types of paper stabilizers, I don't see why I have to buy a selection when the spray works perfectly. Is there a reason not to use the spray?
