SEWING BASICS Select the stitch appropriate for the area g to be sewn. For details on selecting a stitch, refer to "Pattern selection dial" (see page 11). Memo ● When using a twin needle, be sure to use a stitch width of 3 or less. CAUTION ● After selecting a stitch, slowly turn the handwheel toward you (counterclockwise) and check that the needle does not touch the presser foot. If the needle hits the presser foot, the needle may bend or break. Start sewing. h For details, refer to "Starting sewing" on page 23.  Two lines of stitching are sewn parallel to each other. CAUTION ● When changing the sewing direction, be sure to raise the needle from the fabric, and then raise the presser foot lever and turn the fabric. Otherwise the needle may break or the machine may be damaged. Thread tension The tension of the thread will affect the quality of your stitches. You may need to adjust it when you change fabric or thread. Memo ● We recommend that you do a test sample on scrap of a fabric before you start to sew. ■ Correct tension Correct tension is important as too much or too little tension will weaken your seams or cause puckers on your fabric. 2 1 3 4 1 Surface of fabric 2 Back of fabric 3 Upper thread 4 Lower thread ■ Upper tension is too tight Loops will appear on the surface of the fabric.
