Blind Catch Stitch
Used on heavier fabrics to secure hems.
Work from left to right. Begin by securing the thread. Take a small stitch in the garment from right to left then take the needle diagonally over to the hem allowance. take another small stitch from right to left. Repeat the process to create little stitches, catching a thread or two of the garment and hem, and resulting in what looks like catch stitch.
