The knook is a new tool I picked up at the craft store (available at michaels, joann, hobby lobby) and I wanted a nice easy hat pattern that is customizable. well I couldn't find a free one so HERE YA GO. The knook is a crochet hook with a long cord attached on the end. to make the fabric you do a crochet motion (actually like tunisan or afghan stitch) but the fabric is definitely knit. for more help on the actual use there are a ton of helpful videos. this project only uses the basic knit stitch. here is the knook website : http://www.leisurearts.com/products/knook-beginner-set-for-medium-weight-yarn.html
