How to sew on PVC fabric or imitated leather using either a Teflon foot or Scotch (document) tape on your normal pressure foot. :) I've sewn on a lot of PVC and imitated leather (and real leather and other) since I started sewing, and it has taken me a loooong time figuring out how to do it properly, so I hope that this little video will help you on your PVC-sewing way, so you won't get as frustrated as I have been. :) Happy sewing!
