How do you make a makeshift sling for a broken arm in an emergency?
user
The sling is an extremely common item for first aid, and it’s especially useful for injuries to the shoulder.  For more complicated cases you may want to try “buddy straps”, a strap which runs between your shoulders, like a backpack, which distributes the weight of your arm over a larger area of your back.

I don't need the definition. I know what a sling is and how to use it. I want to know what I can use to make a sling in emergency.

Perhaps you have some stretchy fabric lying around?  Does the home have pillowcases or bedsheets?  Or might you have a sweater that you can tear into pieces?  If so, there are a couple of things you might try:

1.  If you’re willing to tear the sweater or other fabric you have, I recommend using the pillowcases.  They have straps on the ends, and this will make it easier to tie the sling.

2.  Another option is to use a sweater, like a pullover.  It may be harder to tear, but it might also have some string on it, or maybe elastic in the waist.  I can tell you more if you say yes.

Of course, I understand that you want to know how to build one out of materials you have on hand.  You can use a piece of cloth, or something like a bandana.  Or a paper bag or paper towel will work too, but you might have to be careful that it doesn’t cut into your skin if you use the sharp creases.
