Testing the Singer 9970 Sewing 4 to 6 Layers of 2 oz. Leather using a size 16 Leather Needle. Be aware that this can throw a domestic sewing machine out of time. I am only demonstrating the power of the machine here. Plus, I know how to repair it if I break something during these test. A domestic machine should not be used to sew leather for business purposes - even it you have a part time business. They are not designed to withstand the stress of sewing leather daily or weekly. For that invest in an industrial or Semi-Professional machine. Plus, your machine must support nylon thread (V69) in order to sew leather successfully. This machine will not support nylon thread.
