The following is a 3 part video series on how to sew a cowl, for superhero or other purposes out of spandex.
I recommend using nylon spandex, or cotton spandex (lycra). Half a yard of fabric will be sufficient. Other tools include; pins, good shears, marking tool (to mark dart) such as chalk, or tracing paper and tracing wheel, and of course a sewing machine and thread.
The pattern is also very helpful too! If you would like a copy of the pattern you can send me a message on youtube, or send me an email with your address to anigswes @ gmail.com and I'll mail you one. Enjoy!
