Warning for bare feet quilters
I did about 6 hours of free motion practice on my old Kenmore without shoes. In the middle of the night I awoke to excruciating pain when my foot tried to stretch out again. Thought I was going to be in the high foot pedal position with pain in the foot forever! It lasted 3 days. I now wear a suportive shoe and take breaks. Best wishes for those of you with strong bare feet. I don't wish this on anyone!
