I seem to recall getting quite irate with one or two projects over the years.. maybe more.
However, the worst I ever got was while trying to adjust the tension on my only machine that does decorative stitches.
Cursing wasn't enough..
If I hadn't stopped, turned it off, unplugged it, covered it and removed it from my sight, it WAS going to become a flying object aimed at the window.
True story.
I ended up taking it in to the Sewing Machine Hospital for professional diagnosis and treatment.
Yes, it was that bad.
