Photos don't do the shapes justice, you'll have to see them with your own eyes. Go make a few and experiment.
Step 1: You will Need...
Nails (or paper clips or coat hanger bits. I picked nails because they were handy)
A small torch or soldering iron.
Soapy Water and string for dipping the shape.
Standard warnings: Fire is HOT, Flux is corrosive, lead-free solder is better than leaded solder. I can guarantee you will burn your fingers picking up a shape before it is cool, because even though I've done this stuff a lot, I still am too impatient.
Step 2: Solder metal bits together into a shape
Some helpful hints:
A third hand is really useful here
You can be sloppy with your solder joints, because these are not bearing any force. It just looks better if you make clean joins.
