I was quilting a queen size quilt on my first machine that I ever owned. It was a Janome that was brand new $200. I was at quilting retreat. I was burning up my sewing machine from high speed quilting. You could smell it. Pedal to the metal was still going very slow. I just threw everything down, turned off my machine, got up, said "good night", and went to bed. The next morning my machine was fine and I started again. Everyone got a good laugh out of it. And over 10 years later, it is still brought up. Bought a new machine shortly after. I just quilted a king size on my machine with no problems. I am ready for a new though with a deeper throat since I tend to make larger quilts, it seems.
