Context: Perhaps it came loose itself with use . I tightened it and got back to work . When I switched to my straight stitch machine , again I found the foot had been unscrewed and was loose . While I do occasionally need to switch feet on this machine , I had done no sewing the day before that would have forced me to unscrew the foot to switch it out .
Question: How many machines do I have ?
Option 0: The one with the loose foot and the straight stich machine .
Option 1: Four machines all with loose foot .
Option 2: None of the above choices .
Option 3: Too many to count them .
Answer: 0
