I own a Singer 9217 model and the tension has gone crazy all of the sudden. I was in the middle of a project and it was fine. While I was in the middle of stitching I noticed a slight catching on the bottom. When I finished my line I noticed the under side of the fabric had loose loops and thread nests where I back stitched. I've tried adjusting the tension and stitch length in both dirrections. Nothing seems to be working. Any recommendations or suggestions? I was told it would be 70-90$ to repair but I needed to finish my project this weekend. Thanks!

I used to get this problem a lot with all my machines. It usually happens when the machine is threaded wrong, even just a little bit. So try rethreading it a few times to see if that helps. Make sure that the tension is proper, and that the tension part is working right.

it really is a matter of getting those tensions right, make sure first of all that you do not have any sharp edges on the needle plate where you may have broken a needle at some poing, with the top tension about 4 or 5 you should get a perfect stitch with a good mercerised thread.
