There are times sewing can be sew not fun. I crack myself up.
My mom gave me her old sewing machine which she must have stored in dust. I did not know that storing it in dust was the preferred thing to do and it was polished on the outside so nicely that I just sat down to use it.
Two broken needles later, my mother-in-law came over to look at it. At my mom's suggestion, we looked at the inside to see if it needed cleaning. We pulled out clump after clump of dust. We think we found the culprit wedged deep inside one of the moving parts. I was a long piece of black thread with several knots in it. Mom, when was the last time you used that machine with black thread? (Clearly before you stored it in dust.)
The machine appears to work fine now.
