At the last quilt guild meeting, one of the sew-and-tellers mentioned that she bought the fabric on Mon, pieced the quilt on Tuesday, basted it by Thursday and then quilted it Fri, Sat, and Mon, but not on Sunday - because one of her clients once told her:
"Every stitch you put in on a Sunday you pull out with your teeth in hell"
The whole room went quiet and then burst into laughter, because the notion is ridiculous of course! For example, I only have time to really quilt on weekends when I don't have to work, so my productivity would be cut in half if I followed the above motto.
It was such a stunning, somewhat scary prediction to hear, especially amongst those lovely quilt ladies, I think we all laughed to release the pressure ;)
