Help with making a paperweight?

[besos.livejournal.com]

I've never made a paperweight before so I need a little help. I was going to make my friend a paperweight as an inside joke/"thinking of you" gift, but I have no clue whatsoever what to make it out of. I know it'll be round a sphere in shape though, and someone I know suggested some sort of recycled steel scraps. However, I wouldn't even know how to go about working with such a material.

What medium do you suggest would be "simple" (& relatively inexpensive) to make a paperweight?

Thanks in advance for your help :)

ETA: Sorry, meant to say I intend for it to be a SPHERE.
