The slip stitch is a hand-sewing technique that is usually used to sew down the fold of a binding edge or a hem. It is nearly invisible! Here’s how to do it…
Tie a small knot at the end of a length of thread and thread it on a needle.
Bring the needle from the inside of the binding or hem’s fold and exit through its crease, leaving the knot tucked inside the fold. Take a tiny stitch directly across from the spot where the needle exited the fold.
Now pick up about ¼-inch of fabric, running right along the crease, as shown above.
Pick up another tiny stitch right across from the last exit point, then travel back through the fold, inserting the needle directly across from the tiny stitch.
Continue back and forth in this manner along the entire length of the binding or hem edge. Tie a knot at the end.
