I'm knee deep in holiday knitting--still (work and school will do that to you, I suppose). I'm trying to get it finished up, and have decided to knit this lovely cowl courtesy of http://lilibethsgarden.wordpress.com/2009/11/17/chunky-lacy-cowl-pattern-free/. However, I'm having a bit of trouble. The pattern specifies using a size 13 18" circular needle to knit the cowl. Alas, I was unable to find a circular needle that was 18 inches long in any of my local craft stores (Joann's, Michael's, and Hobby Lobby), nor do I have an LYS near my home. So, I decided to buy a 16" one as the pattern states "18 in. or there abouts." I was wondering if I cast on more stitches than needed in the original pattern if it would still be the same circumference as the cowl knitted with the 18" circular needle.
