Probably a silly question, but I don't know the answer. I have sewn a couple of projects using the two needle method (saddle stitching?). I think that sewing with a single needle would be easier for me. For the saddle stitch method I use a diamond shaped pricking iron - what kind of holes should be made for stitching with a single needle? Is their a pricking type iron available for the holes? Any help will be appreciated.
