I have a treadle that I purchased several years ago for $100. Its a 'Cadillac" top of the line, gorgeous cabinet, 6 storage drawers. I taried sewing some polyester fabric on it and it skipped like crazy. It sews fine on cotton! My hubby reminded me that they didnt have polyester when they sewed on those machines. lol I guess he was right (again) I have plans to make a simple 9 patch quilt on it.
