Sewing thick fabric
When sewing over thick fabric, the
presser foot may tilt and be unable to
feed through the fabric.
Place fabric or paper of the same
thickness as the fabric you wish to
sew under the presser foot. This will
enable smooth sewing.
Sewing thin fabric
When sewing thin fabric, sometimes
fabric puckers, which is an
indication of incorrect feed.
In such a case, sewing is easier if
tissue paper is placed under the
fabric.
After sewing, remove the tissue
paper carefully.
