A simple yet elegant way of displaying a meaningful or pretty stone you've found, using only some copper wiring.
Step 1: Wrap
There is nothing more to say, besides watch the sharp ends of the wire and wrap in a bunch of directions on different faces. Make sure to keep it varied. Another idea is to vary wire types and sizes, giving an airy depth to the paperweight.
Step 2: Paper the Weight
Now use as a paper weight, or just decoration. Suit yourself :).
