I have a 15-88 treadle that I am teaching myself to fmq with rulers. I have been using it for piecing and I have quilted a wall hanging on it with a walking foot and a lot of other sewing. Just a lovely machine. I learned to sew on my moms 15-91, which she bought after learning to sew on my grandma's treadle. She got such a kick out of me having a treadle, she told me that she bought an electric machine as soon as she could afford one:-) One day that machine will come to me as well.
