Step 1: Materials
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
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
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.
Step 4: Attatching
On the other end make a half of hook to join the two.
This is fairly simple
