The needle should suit the thread. When sewing the thread is fed through the long groove in the needle. If the needle is too fine, the thread does not fit into the groove and stitches will be skipped. Use needles no. 70-90 on your Bernina overlocker. E 3 Thread/decorative threads Sewing and overlock threads are being manufactured in increasing numbers in a wide variety of types, weights and combination fibres. It is worth investing in good quality threads for perfect sewing results. Decorative threads specially made for overlockers are also becoming widely available. We recommend following the basic guidelines when using special threads on your overlocker: - Purchase threads which are exclusively produced for overlocking on cones or spools. - When using normal spools, use the spool caps (in accessory bag). - Only use decorative threads in the loopers. Thread must move easily and without resistance through the thread guides and looper eye so take this into account when purchasing thread. - The thicker the thread, the longer the stitch length. - The thicker the thread, the looser the tensions. - Sew slowly when using decorative threads. Pull the thread chain gently backwards when starting to sew. Always test sew when using decorative threads. - Use the deco-guide when sewing thick or decorative threads.
