Step 7: Threading Tips for the Serger • • • • Use good quality serger thread. This thread is sold in larger 3000 yd. spools at most fabric and sewing retailers. Use the same brand of thread in all tensions, do not mix and match brands. Use the same size spools on all cone adapters that are located at the back of the machine when threading your serger. Try to avoid black thread; it tends to cause static, leading to skipped stitches. Use a dark grey or navy instead.
