Smocking Smocking is achieved by sewing numerous parallel seams across your fabric to create a gathering effect. Smocking is mainly used in children's wear and heirloom techniques. There are different methods of creating the smocked effect: V mg. vn4v 5 il 2020 • 1 0 2.5 / 35 0 2010 )2 72 , • 16 6.0 2.0 / _ 3 5 7(Ir 4 2010 0 1) Smocking with gimp thread (non-elastic) For beautiful smocking effects you will need two and one half to three times the desired finished width of fabric. The smocked section is usually made before the completion of the garment. Light, firm materials such as batiste or fine linen are best suited for this technique. Using a fabric pen, or other non-permanent pen or chalk, draw a straight line on the fabric as a guide for the first gathering seam. Attach the sewing foot (the special accessory applique foot also works well): loosen the screw at the rear end of the sewing foot holder and insert the edge guide through the opening. Position the edge guide 1 inch (2 - 2.5 cm) from the needle and tighten the screw. Place the fabric to be gathered under the sewing foot, right side up. Position the gimp thread under the sewing foot so it runs exactly along the groove at the center of the foot. Sew the first gathering seam, leaving approximately 4 inches (10 cm) of the gimp thread at the beginning and end of the seam. Place the edge guide on this stitching line -the next row will sew approximately 1 inch (2 - 2.5 cm) from the first row. Different spacing will achieve different gathering effects. Continue to sew the remaining rows using the edge guide for spacing. Carefully pull the ends of the gimp thread and gather the fabric evenly over the entire fabr:c width. - wog. .. , vvv - ....... -.06.- ( ,= 10 J1_ 2020 /• 1 0 2.5 3-5 0 2010 2) Smocking effect with elastic threads For this technique, elastic thread is wou9d onto the bobbin without tension. The needle thread may be a regular sewing or an embroidery thread. Since elastic threads are much thicker than normal bobbin threads, the tension on the bobbin case must be set extremely loose. However, the tighter you sot the bobbin-thread tension, the greater the gathering effect you will obtain. For this kind of smocking, fine and light material such as lightweight knit fabric, silk or sa:in are also suitable. Mark the first lino on the fabric to be gathered. Sew along this line and knot the threads at the beginning and end of the seams. For the remaining parallel seams the material must be stretched to its original length during sewing (do not overstretch fabric).

Hemming prevents the edges from fraying and produces a neat and durable edge finish. Double-fold the fabric edge (about 1/8 inch / 2 mm per fold). Place the folded fabric edge under the hemmer and sew a few stitches to secure. Turn the handwheol towards you until the needle is at its lowest point. Raise the sewing foot and slide the fabric into the scroll of the hemmer. Lower the sewing foot and while sewing, guide the fabric edge evenly into the hemmer. When roll-hemming, make sure the raw edge of the fabric butts against the left edge of the hemmer opening. Ensure the fabric does not run underneath the right side of the sewing foot. prou. vw v 5 2 -Y-i- (1(I c> J1- 2020 y 3 1-3 1-3 3-5 / 2010 Program 3 A narrow zigzag stitch else makes a nicely finished rolled hem. 55
