25. HOW TO SEW A COVER STITCH
This machine can produce a 3-thread 5.6 mm wide bottom
cover stitch.
The cover stitch can be used for covering, binding or top-stitching
necklines and for hemming the bottom, of T-shirts and sweat suits,
etc. in addition to flat joining seams (plain seaming).
The cover stitch is most suitable for stretchy fabrics such as knit.
It also can be used in woven fabrics such as denim, but careful
attention must be paid to the tension settings or there is the
possibility of thread breakage and or skipping.
If you experience skipping or thread breakage sewing denim
change needles first and then adjust the tensions little by little
(1/4 number at a time).
