How to balance a mobile... and attach its parts?
I've always been interested in making mobiles, or at least making the various parts that I would like to balance in a mobile. I've only really made one, which was a real hack job. I want them to look nice, so...two questions:
1) Is there a scientific method for achieving balance in a mobile apart from guessing? In the one that I did make, I used a fairly thick flower-wrapping wire, tied the parts to each end, and then found the fulcrum by balancing it on my finger. This is an awfully rough approach and is only so accurate. It worked okay, but I'd like to know how you've found success in doing this.
2) As far as attaching the parts to the end of the wire, how do you do it? I'm not very happy with the flower-wrapping wire because it's so tender and warps so easily. It's impractical for shipping or moving the mobile. Not at all durable. So what material do you use for the wire portion, and HOW do you attach your parts to it? I've tried twisting loops into the wire, but it really messes up the general straightness of the wire. I've tried tying fishing line onto the wire and adding a dollop of glue. But that's just ugly.
If you have a good online source for making simple mobiles, and the materials one should use, I'd love that too!
