I just went upstairs and was messing with the bobbin case. I take a piece of dental floss every once in a while to the upper tention to make sure there are no little fuzzies that are stuck in the tention disks. I thought, why not the bobbin case?? I took a piece of the floss and ran it through the tention part of the case and out came a minut piece of fuzz. Did several tests on fabirc of all thinkness and folded, refolded and sewed many, many samples, No more loops on the back of my project. Saved me 40.00 for a while anyway...
