I just recently had surgery on my hand and knew beforehand that I would have a cast for a couple of weeks. i had no idea if my cast would fit through the sleeve on any of my jackets so decided to make myself a poncho. I saw one similar on Pinterest that had been pinned. I remembered using apattern several years ago to make my daughter a similar one. It is simply a rectangle with an opening for the neck. I didn't have enough fabric so I had to put a seam on one side. I also thought a monogram would add some interest.
