Woohoo! Finally got this tutorial done. This makes a very smooth, clean and stretchy finish to a 1x1 ribbed edge or even a seed st. edge.
Cut length of yarn about 4 times the length of the edge you are binding off and place on a tapestry needle (you'll want a good strong one like a chibi).
1. Insert tapestry needle knitwise into the first stitch, pull stitch off needle.
2. Insert tapestry needle purlwise in the the second stitch from the end, leave on needle.
3. Insert tapestry needle purlwise in the first stitch, pull stitch off the needle.
4. Coming from the back, insert needle knitwise into the second stitch from the end (this is the trickiest part), leave on needle.
Repeat 1-4 until you get to the end. Voila!
