5 Thread 1/4" A 5-thread 7mm (1/4") stitch provides a narrow seam allowance. It is great on lightweight woven fabrics, making it ideal for quilt piecing. The formation of the chainstitch makes a very stable, secure stitch. The narrow overlock stitch is a great edge finish. The stitch is a strong durable construction method for woven fabrics. 5 Thread 1/2" A 13mm (1/2") seam allowance using a true 4-thread stitch consists of a 2-thread chainstitch and a 2-thread overcast. The formation of the chainstitch makes a stable, secure seam. The overcast stitch uses less thread for a finer finish. Sew on woven fabric for garment construction or home decorating items. Excellent for drapes because the long seams are stable and lightly finished. 4 Thread 1/2" A 13mm (1/2") seam allowance is great for woven fabrics. The chainstitch provides a stable, secure seam and the 3-thread wide overlock stitch is a great finish for the edge. The 5-thread stitch, commonly used by ready-to-wear manufacturers, is only 10mm (3/8"). There is now enough seam allowance for future alterations. Sew, trim and finish in one step.
Compatible with Elna overlock models 945, 925, and 905.
