Pat: Thanks so much for the information on treadle belts. Yes, the belt is VERY old and hasn't been tightened in 30 years at least. Do you have the name of your friend in Mn. where you get your supplies? My first sewing project on this machine was hemming cotton dish towels and from there I went to putting purchased bias tape on Mom's aprons. Wow - that's dating myself.
Enjoy the day, Phyllis in Minnesota
