If you were out on the road trying to get home, you could boot that tire with just about anything and get home on it. But I wouldn't use that tire with so many cut threads in the casing for anything longer than it takes to acquire a new tire.

A boot is just something you put between the tube and the hole. It can be a folded up 1 dollar bill, though 100 dollar bills are more impressive when you tell your friends. Or it can be a piece of tuff fabric like sail cloth or a piece of a plastic bottle you found on the side of the road and cut to shape.

In all cases, I'd consider a boot a very temporary repair. Mostly just for the purpose of getting me home or somewhere to get additional help.
