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.
*Use the same thread for needle and bobbin.
*When sewing stretch, or fine fabrics and synthetics, use a BLUE SHANK needle. The blue shank needle
effectively prevents skipped stitches.
*When sewing very fine fabrics, sew over a piece of paper to prevent yarn distortion.
