1. I usually begin this step by cutting a piece of the thicker wire to a reasonable size for a 3cm tall mini (a little more than 5cm long). More is better than less because you can cut off the excess
2. Use the two pliers to bend the wire to the desired shape of half the body. What I mean by this is, bend the wire such that you get a leg, the torso and an arm out of it. This is the most important part of the mini because it acts as the main skeleton. The thinner wire can then be attached to the thicker wire to make the other arm, leg and weapon if need be.
3. Strip a twist tie: Scrape it a bit with the pliers and it should remove the plastic or paper that's immediately above the wire, you should then be able to grab the wire and rip it out of the rest.
4. Twist the wire into the desired shape using pliers. You may want to wrap it around the torso a few times to secure it.
5. Pose the armature.
You'll notice that I didn't make anything for the head. I usually just make the head out of regular super sculpey so it binds without a problem and doesn't really need the armature to be secured.
