I've gotten to the point in my clapotis where I start to drop stitches to create the pattern. I am almost certain I'm going to need more yarn than I originally bought.
I got Vogue Knitting and a $50 gift certificate to a local yarn store for Valentine's Day. The stitch dictionary in Vogue Knitting is amazing. I know I'm going to me using it as a reference for years to come. (Thanks, honey!)
