HOW TO SEW A COVERSTITCH
– This machine can produce a 3–thread 5.6 mm
wide bottom coverstitch.
– The coverstitch 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 coverstitch 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).
