5. To Secure an Improvised Arm Sling
There are countless videos and tips for using a t-shirt as a makeshift arm sling, but they all make one major mistake: they assume you will be able to tightly tie the t-shirt or other material.
This may not be possible for a number of reasons, and it is also imperative to make sure the sling will not fall quickly apart and further damage your arm. Using safety pins will give you more durability.
You can even pin them through the tied material for extra strength!
