The Back Stitch is excellent for securing seams. It is a super-strong hand stitch that can replace machine stitching when required. It is much stronger than the regular Running Stitch, though it uses more thread. The Back Stitch looks beautiful when it uses small stitches and maintains length consistency. The length of the stitch depends highly on the size of the pattern, though. A small pattern will call for small stitches than a bigger pattern.
