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?

The fabric is thicker on one side (near the edge?) and feeding at a
different speed?

Also check bobbin tension and feed tension are the same (although I can't
quite see why that would affect it).


The tensions all seem to be OK (or so I'm told!) and the fabric
thickness is uniform (the slit is cut after the edging is finished) BUT
a suggestion to control the digital right foot and to sew at a lower
speed seems to have helped significantly so it may be technique (lack
thereof). Experiments continue.
