Cowl's are the simplest and fun knitting project!
All you need is a circular needle, any size depending on how thick/loose you want your project.
CO 100+ stitches, depending on the size of your needles and how loose you want your cowl. For mine, I used size 6 circular needles and 100 stitches in a seed stitch with rotating Griffindor themed colors from Harry Potter. Continue in the round until your project is about 18 inches long. If you want it really slouchy, make it longer. The great thing about knitting with circular needles is that you won't have a seam.
