Refer to these tips when sewing your project. Trial sewing A trial piece of fabric should be sewn. Use a piece of fabric and thread that are the same as those used for your project, and check the thread tension and stitch length and width. Changing the sewing direction 1 When the stitching reaches a corner, stop the sewing machine. Leave the needle lowered (in the fabric). If the needle was raised, lower the needle either by turning the handwheel toward you (counterclockwise) or by pressing once. CAUTION • When using the twin needle, be sure to raise the needle before changing the sewing direction. If the fabric is turned while the needle is lowered, the needle may bend or break. 2 Raise the presser foot lever, and then turn the fabric. Turn the fabric using the needle as a pivot. 2 3 4 1 Wrong side 2 Surface 3 Upper thread 4 Lower thread 5 Loops appear on wrong Solution Increase the tension by turning the upper tensioncontrol dial to a higher number. 54 3 28 3 Lower the presser foot lever and continue sewing.
