Welcome to the Quilting Board!
Candace sent a pic of how it should look done - that thing is a real bugger - I'm thinking a magnet or something to hold it in place maybe so it doesn't fall out before I get it anywhere near the machine. This one is more than holding your mouth right and not letting any swear words leak out.
Never let a sewing machine know you are in a hurry.
I was cruising thru yard sale pictures in Atlanta and found this...looks like they don't much care about the treadle wxcept as a stand for the china! I'm not in the market..
