When your friends see you wearing the arm sling, sure they will ask you how you broke your arm. If you answer once or twice, it’s still fine but you will feel very irritating if you have to repeat and repeat the same story whenever you meet your friends. You know, your friends are very busybody…so you need this “illustrative arm slings,” you just need to point to the image, let it answers for you.

The picture above shows four scenarios on how you broke your arm. I don’t know exactly how many designs they have but just in case you can’t find a best image that describes the accident, draw it by yourself, with your broken arm!
