Capes are awesome. They're fun to wear, work with lots of styles, and are super easy to put together. I guess the downsides are the amount of fabric they use and how they choke if they slide back. I tried finding information on stopping this, but short of attaching the cape to clothing underneath I can't find much - guess I'm not cut out to be a superhero.
Over the past couple weeks I've made 3 very different capes, using zero patterns and vague measurements:
1. I have to get to dress up for work on the weekends from now till Halloween, and when I saw this cheap red velour I thought it would be great for Little Red Riding Hood. It's a bit scratchy on the neck seam so I'll probably have to wear something with a higher collar underneath, but I like the look. This "pattern" is a half circle.
