I took a class for 2 Saturday afternoons at my LYS. I'd tried doing it before from directions I'd found on the internet, but couldn't seem to figure it out. Having someone show me what to do is the best way for me to learn new techniques.
Sunny...the technigue is NOT hard, but at first it was confusing trying to figure out where to start after I'd put it down for a while. I had to put myself a sticky note on the shawl so I would know what to do. There's a lot of turning back and forth, but it's just knit and purl and picking up. Nothing really fancy to learn at all. Try it....you'll be amazed how fast it goes.
