Useful Sewing Tips ■ Sewing cylindrical pieces Removing the flat bed attachment allows for free-arm sewing, making it easier to sew cylindrical pieces such as sleeve cuffs and pant legs. Pull the flat bed attachment off to the left. a Slide the part that you wish to sew onto the free arm, b and then sew from the top. Sewing an even seam allowance To sew an even seam, start sewing so that the seam allowance is to the right of the presser foot, and the edge of the fabric is aligned with either the right edge of the presser foot or a marking on the needle plate. ■ Changing the needle position The needle position used as the baseline is different for the straight stitch (left needle position) and the straight stitch (middle (center) needle position). 1 2 1 Straight stitch (left needle position) 2 Straight stitch (middle (center) needle position) When you are finished with free arm sewing, install the c flat bed attachment back in its original position. When the stitch width of the straight stitch (left needle position) is set to its standard setting (0.0 mm), the distance from the needle position to the right side of the presser foot is 12 mm (1/2 inch). If the stitch width is changed (between 0 and 7.0 mm (1/4 inch)), the needle position will also change. By changing the stitch width and sewing with the right side of the presser foot aligned with the edge of the fabric, a seam allowance can be sewn with a fixed width. 1 Stitch width setting 1 2 Distance from the 0.0 2.0 5.5 7.0 needle position to the right side of the presser foot 3 12.0 mm (1/2 inch) 4 10.0 mm (3/8 inch) 5 6.5 mm (1/4 inch) 3 4 5 6 6 5.0 mm (3/16 inch) 30.866 mm30. mm 2 • For details, refer to "Setting the stitch width" on page 38. ■ Aligning the fabric with the stitch guide foot (sold separately with some models) Sew while keeping the right edge of the fabric aligned with a desired position of markings on the stitch guide foot. 1 2 3 1 Seam 2 Stitch guide foot 3 Markings 40
