Y-Seams & Miters

When you’re working with a three-way or Y-seam in patchwork, stitch the top two seams of the “Y” first, stitching toward the center intersection of the three seams and back stitching where they meet. Stitch the bottom seam last, again stitching from the outside of the unit toward the intersection and back stitching at the intersection in the middle. Use the same stitching order for a mitered border; after all, it’s just a big, overgrown Y-seam, right? Stitch using this order and direction and the bias edges won’t stretch as much and the pieces will fit together better.
