Information
This machine was given to me. Is this model considered a light industrial? I have a consew for leather with a walking foot and it will not sew light weight leather or lighter fabric. It doesn't feed it through like it does the leather and heavier materials. Is this brother machine more appropriate for lighter fabrics/leather? It has a regular pressure foot on it. Any information would be nice. Thank you.Pat Miller
