What is an overlock stitch? For knit and other stretch materials, the Creative offers a selection of overlock stitches. These join two layers of fabric and serge them in one opera tion. They have a higher elasticity than usual stitches, they are more durable and what is more, they are very fast to sew. TIP: We recommend using blind stitch foot No 3 when sewing overlock seams. This guides the fabric better and prevents tunneling of the seam at wider stitch widths. Closed overlock stitch with edge thread Prog. 06 If you wish to sew a material that frays easily, select program 06. With this stitch an additional edge thread protects the fabric edge against fraying. Open overlock stitch Prog. 29 With this stitch it is easy to join firm materials or fabrics which do not fray too much. TIP: Make sure that the needle at its farthest righthand position just misses the edge of the material. Closed overlock stitch With program 25 you can sew jersey-quality fabrics perfectly. You can also sew on cuffs and collars extremely durably with it. TIP: Make sure that the cuff is stretched while sewing. Pullover stitch Prog. 20 Used together with the knit-edge foot (special accessories), this stitch can even be used for openknit fabrics. Fashion-knit garment sections can also be joined effortlessly with this stitch. TIP: To prevent the seam from stretching while sewing, it is advisable to add a woollen thread or length of yarn under light tension. 67
