Bias Sewing Machine Attachments

… Because of the age of my industrial sewing machine there is no way to attach to the machine. I have 4 different sizes. $20 each or $48 for all. These are long shank NOT short. These are primarily made for industrial sewing machines. Measurements are 3/8" (1-1/2" strips) 1/2" (1-3/4" -- 1/2") 5/8" (2"-- 5/8") 5/8" (1-5/8" -5/8")
