Selection Of Needle
•
in general, fine threads and needles are used for sewing thin fabrics, and thicker
threads and needles are used for sewing heavy fabrics. always test thread and
needle size on a small piece of fabric which will be used for actual sewing.
•
use the same thread for needle and bobbin.
•
When sewing stretch, very fine fabrics and synthetics, use a Ball pOint needle. the
blue tipped needle effectively prevents skipped stitches.
•
When sewing very fine fabrics, sew over a piece of paper to prevent fabric distorting.
