Sewing machine jams when I use thicker threads
This is my second time trying to use a thicker thread for hemming jeans, and the thread jams instantly on the first stitch. I have a Kenmore; it's a pretty good machine. I'm self-taught, so wondering if I'm not doing something right.
I'd like to use the thicker thread because it matches the thread in my jeans. It's Gutermann thread, so I think a high quality thread. Any ideas, or should I just chalk (chock?) it up to my machine not being able to handle anything other than standard thread?
