OK chaps and honourary chaps, here's a question about DIY sewing. SWMBO
is trying to sew buttonholes using a buttonhole attachment on a Singer
Talent sewing maching. The thing goes through the process of zigzag
stitching down one side and back up the other but the zigs (or zags?)
are more widely spaced on one side than t'other. I can't find a user
adjustment anywhere so am wondering whether it's an internal set-up
issue or a technique issue. Are there any sewing machin experts out there?
