Instead of pearl cotton thread you can also place a different colored light fabric underneath. .411> Key i=cp "Pattern mirroring" Shell edging Shell edging is very effective for thin, soft fabrics such as silk and rayon fabrics. It is frequently used as an edge finish on undergarments. Select blind stitch No.5 and mirror it with the "Pattern mirror" key. The tighter the needle thread tension is set, the farther the shell edging will pull in. Serge the raw edge and press the seam allowance to the left. While sewing, make sure the fabric runs under the sewing foot at half of the foot width. This provides a more prominent shell edging effect. Buttonholes Your tiptronic offers you two ways of sewing buttonholes. 1. Fully automatic buttonhole - the width, length and stitch density can be altered. 2. Semi-automatic buttonhole - the reverse seam is determined during sewing of the first buttonhole. All other buttonholes are fully automatic. The semi-automatic buttonhole is important for sewing accurate buttonholes on difficult fabrics. The following tips will enable you to sew perfect buttonholes even on these difficult materials: - Buttonholes that have been inserted very close to a reinforced edge may sometimes nol feed as precisely with the buttonhole foot. In this case use sewing foot No.1. - Materials that shift or stretch easily should be reinforced with Avalon (embroidery nonwoven from Madeira), tissue paper or other lightweight stabilizer. - Keyhole buttonholes become particularly stable and durable if a gimp thread is inserted during sewing (see "Keyhole buttonhole with gimp thread"). - Linen buttonholes become particularly dense and attractive if you use embroidery and darning thread. - Buttonholes are normally selected a little larger than the button diameter. It is important to always sew a test buttonhole on the same fabric/stabilizer as your project. 58 59
