This brings back a great memory and I'm sitting here chuckling to myself. My quilting buddy Dina and I signed up for a class which was a little too advanced for us. We decided to be cool and go with the flow. After sweating over some tough cutting we started to sew our blocks. All of a sudden Dina starts complaining that her machine just wasn't sewing right so I tried to help her. We fussed, fiddled and adjusted but no stitches. . . . until a fellow classmate pointed out that it would probably work better with a spool of thread. Boy were we embarrassed. To make matters even worse we got to laughing so hard we were in tears. It's a wonder we weren't booted.
