The following tips will help you work with knitted fabrics. Join the seams with narrow zigzag stitching (stitch width ½ to 2 mm, length 3 to 4 mm). Some sewing machines have special jersey stitching, see you machine’s instruction manual. Over-lock machines are ideal for working with knitted fabrics. Your sewing machine will need a special jersey needle that has a rounded point to prevent damage to the knitted stitches. Neaten/finish the edges of the seam and hem allowances with large zigzag or over-lock stitching. If the fabric stretches too much, stick adhesive tape on the outer edges and then edge-stitch along before trimming off the adhesive tape. Stretch out any rolled collar, narrow neckline or rib-knit cuff band while stitching. The hems will remain stretchy if you topstitch the hem allowance with a twin needle which produce a double line of stitching on the right side and elastic zigzag stitches underneath. Hand-sew the hem with loose slip stitching and fold the upper edge of the hem allowance back by ½ cm. If seams are not intended to stretch, catch in a strip of bias binding with the stitching. Armholes can be chain-stitched along the seam lines. Or iron Vilene/Pellon seam band on the fabric, over the marked seam lines. Snip into the band around curved sections. Strengthen edges of fastenings with fusible interfacing.
