need help with featherweight problem
Hi all, need some help with my featherweight. It's been working fine for the couple of years I've had it, but now it's acting up. I'll be sewing along just fine, and now, all of the sudden, the needle hits the throat plate. The first time this happened, I backstitched and when I went forward, the needle struck the throat plate. I have checked everything I can think of, bent needle, needle size, threading, etc. Still doing it after 10 to 20 stitches. Also, I do not tug on the fabric or pull on it. Any help anyone can give me would be appreciated. Thanks.
