The Jig Stitch is my adaptation of a slip stitch pattern sometimes called Flame Stitch. I added a little twist that prevents an open hole in the fabric. I use it in two of my patterns- The Happy Dance Hat and happy dance mitts. I love the zig-zags as they remind me of Ric-Rac trim.
It's a four stitch , four row repeat. The only possibly tricky row is row 1. It's my hope that this little video demo will be helpful.
