Wear a nice Barbed Wire necklace, or bracelet.
Caution: I am not responsible for any injuries

Step 1: Materials

Only two materials this time ;)

Wire
Wire Cutters

I had both of these, but you can buy wire for like $3.00, and the cutters for $7.50ish

Step 2: Making the Base

To make the base of the barbed wire, measure a piece of wire around your neck (a little lose).
Then cut.
Make another piece of wire the same length.
Twist the wires together.
Now now you should have one piece of wire twisted.

Step 3: Making the Barb

To make the barb,
first take a piece of uncut wire, and lay it up against the base.
Next, leaving a centimeter sticking out, start to twist around the base.
Do that three times, so you should have three loops.
Leave a centimeter on that end as well.
Make sure that the ends are opposite of each other!

Do that as many times as it fits on the base. You made your Barbed Wire.
