How to make a hat really easily in 5 minutes.

All you need is:
An old scarf or some cloth shaped roughly like a scarf
A paper clip (or 2)
And a metal file

Step 1:

Un-bend paper clip so it has 2 hooks on either side.

Step 2:

Now file the ends so they are sharp, doesn't have to be sharp enough to use as a fish hook.

For knit cloth you probably don't need to sharpen it at all.

Step 3:

Double over the cloth at one end of the cloth and insert one side of the hook into the fabric.

The small hook is probably better this way there is more room to hook the big one at the end.

If you are using 2 paper clips you probably want to attach them toward the edges.

Step 4:

Now grab the unhooked side and wrap the cloth around your head and then when you run out of cloth use the hook to attach the cloth to your new hat so it doesn't unravel.

Note: If you already have some sort of hat like me just pull it over your new one if you want to be extra warm.
