I use the Russian Bind-Off (at least, that's what I'm calling it) in my newest design, Tempest Shawlette, and thought you'd appreciate a brief photo tutorial on how it is done....
Step 1: With the right side facing, purl 2 stitches together through the back loop (p2tog-tbl).
Step 2: That leaves one stitch on the right needle.
Step 3: Slip the last stitch back over to the left needle.
Repeat Steps 1-3! Easy!
When you get to the last two stitches, purl them together through the back loop. Then, cut your yarn and pull the tail of your yarn through the stitch.
