In this video I show how to successfully sew a true flat felled seam on a jeans back crotch. This seams to be the hardest seam to do on a curve. It does take some time, but the results are worth it. This method can be used on any pair of pants as well. You may see the white thread close to the edge of the fabric. That is a stay stitch to keep the curve from stretching.
