When you run the Shirley stitcher, it automatically goes into constant speed. The shirley stitch is turned off. I have left the Shirley stitcher on for 2 days, because if I turn it off I will lose everything. I set it up to do 5 rows of pantos with 9 patterns across. When I turn it back on my stitch box will be a different size. So setting up new pantos will turn out to be a smaller size. I'm down to the last 11 inches of quilt. But turning everything off maybe that might set everything back??? This is probably wishful dreaming.
