*Use the same thread for needle and bobbin.
Note: *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.
*When sewing stretch, very fine fabrics and synthetics, use a STRETCH needle. The STRETCH
needle effectively prevents skipped stitches.
*When sewing very fine fabrics, sew over a piece of paper to prevent yarn distortion.
CHANGING THE NEEDLE

its highest position.

towar ds you. Remove the needle from the clamp.
