Curls are marvelously flexible, wearable wraps that work with any weight of yarn, can be knit at any gauge, and look beautiful at any size. Knit them small and wear them as a cowl. Keep going to make a scarf. Do a bit more, and you've got a shawl. They form a wonderfully curved shape that drapes beautifully around your neck and shoulders and can be worn in lots of different ways. Use your favorite yarn, and knit at whatever gauge gives you the fabric you like best. You're in charge, you can't mess it up, and you re going to love the result!
One small note, the structure of these pieces lends itself much better to charted instructions than to written out instructions. So please be aware that all the patterns use charts. If you're new to charts, never fear. There is a lovely introduction to using charts at the front of the book. Read through it, and you'll be ready to go in no time!
