Good news! I didn't have to take my sewing machine to the repair shop. My mom fixed it in about 2 seconds. She took the spool off and found that the thread was wound around the base. Mmmmm I tried re-threading the machine but didn't think of taking the spool off. She tested it by sewing a few items and everything was fine.
What I know about sewing couldn't fill a thimble...but I can now finish my pillows.
