Step 1: Crochet EIGHT granny squares. Mine measured about 6" x 6" each. You can find a great tutorial for granny squares here if you haven't made them before.
Step 2: Lay them out in 2 rows of 4 squares, in a pattern that you like.
Step 3: Take the bottom left square and flip it vertically to lay face to face with the square above it. Now simply hand sew the two together along the one edge with yarn in a matching color and a yarn needle.
Repeat the step with each bottom square in your layout, so that you have 4 sets of 2 squares sewn together.
Step 5. Sew the two ends of your "scarf" together to make a round cowl. Turn inside out.
There's your new neckwarmer! You can make one out of one solid color, or use as many colors as you like! I think this would be super nice underneath your winter jacket, or with a tee shirt & cardi in the springtime for extra coziness. Enjoy! 🙂
