Today’s seam is somewhat of a variation on the French Seam. Unlike the French Seam, a Self Bound Seam is worked on a completed seam. So if you decide down the track that your seams would be better off enclosed, as long as your seam allowance is wide enough you can do this. Great when you don’t have the time to finish them off now, but want to wear your garment out tonight!
Ideally, you want to start with a 12 – 15mm (1/2 – 5/8″) wide seam allowance. If your seam is thinner, you may just find the pressing a bit fiddly. Sew your seam with right sides facing and press it to set the stitches.
*On lightweight delicate fabrics, it’s a good idea to place a pressing cloth or piece of brown paper between the fabric and seam allowance to prevent a pressing line showing on the front of the garment.
