We will create a "rib" topstitch all around the bob to obtain a well-structured cut.
❓ What is a pintuck? It is a decorative stitch, also called a "hair stitch" (but it's rare honestly), which is sewn 1 or 2 millimeters from the edge of a fabric (or a fold). Beyond its purely decorative function, the pintuck can be used to reinforce a seam, to flatten an area, or even to keep a seam lying in one direction (our case here with the bob for example).
❓ How to make a rib stitch? We position ourselves on the right side of our work and we come to sew with a straight stitch, all along our fold / our seam, at a distance of 1 or 2 millimeters. There is therefore nothing very complicated, the only difficulty with the rib stitch is to make it as regularly as possible (perfectly parallel to the fold / to the reference seam).
- Position yourself on the right side of your work
- Stay on the straight stitch of your machine and adjust your settings if necessary: If your fabric is thick, increase your stitch length slightly. This is because the needle now needs to pass through 3 layers of fabric (the Side + the Side seam allowance + the Top seam allowance) and not two as before.
- Place your needle right on the side seam to start. Sew with a straight stitch along the entire length of the seam we just made, 1 or 2 millimeters apart and keeping the seam allowances firmly pressed against the side. Remember to make your backstitching stitches at the beginning and end of the topstitching, as you would for a normal stitch.
- Go back and repeat this step for the second bob base.
