Simple Loop with wire and headpins 
1. Place beads onto the headpin and leave approximately ½ inch of extra wire (more for larger loops).

2.Hold the end of the wire and bend it towards you at an angle of about 45 degrees.

3. Place the round nose pliers into the angle where the wire comes out of the bead.

4. Once again, hold the end of the wire and bend the wire towards you, rolling it over the pliers.

5. To complete your loop take the round nose pliers out and place the bottom jaw back into your semi-loop, then wrap the wire in a downward motion around the bottom jaw of the round nose pliers until the wire crosses.

6. Cut off the excess where the two wires cross. Use the tip of the flush cutters to get in real close.

7. Place the open ended side so that it sits next to the other wire.
