People love you! Wear your helmet! And now you can do so and also be warm when it’s chilly outside. This cowl has a simple slipped-stitch motif and straps that are specifically designed to go through the holes in a Bell helmet (the kind I have). If you have a different kind of helmet, I would suggest looking at it, gauging the placement and size of the holes, and then use that information to decide where to place your straps and how wide they should be.
Edit! The first and second rows should read as follows: k4, wyif s1, k4, p1, and the second should be k4, p1, k4, wyif s1. And then of course, I forgot the garter stitch border on the top!
