I am amazed at how many machines are capable of treadling. I'm looking for a decent machine will decorate and that can hand crank. Those 3 machines Joe and I tested out would hand crank but aren't all that decent with the stitches. I don't have patience for that. I think those were early junk. Lots of stamped metal. What the cams ride on or read with isn't all that good. All three machines worked about the same as far as that goes. One of mine wasn't feeding fabric consistently. I haven't really had time to go over them much though. I would hate to see a beginning sewer try to use one of those machines - probably write off sewing forever.
