I counted stitches better...
and used a thick & quick yarn.
At first I was only using crochet for small things that went round and round or long skinny things. Now I'm enjoying it for the square things also. Crochet seems more fluid than knitting.
Anyway, like I said once I had the pattern ingrained in my mind this scarf went fast. It's 22" folded, 44" around and 13" tall. Four colors, oatmeal, light gray, charcoal and black. Obviously it took 4 skeins but it would only take 2 to complete this project. The pattern is below on the Lions Brand website.
