A group of us get together once a month to make charity gifts. One of the gals had loaned out her extra machine to one in the group to use at home while that gal's machine was being (fixed). LOL The gal brought it back to the group, and it just sat until a new member couldn't bring hers. The "loaner" machine took two stitches, and came to a grinding halt. Some of us know just a little to be dangerous, but we checked the bobbin, and there was a small piece of thread. It still didn't work, but we did find sooooooo much thread caught in the up take it was almost knotted in there. Denim pieces, metallic thread, and oil that we couldn't even cut out. The borrower said, " it worked great for me while I was sewing my heavy denim with all the accessories I needed." It cost the loaner outer over a $100 to have it fixed. We never did see what the borrower made. NO I DON'T LOAN ANY OF MY MACHINES!!!!!
