One to the next one!

The next project I will be embarking on for Sculpture Class is part of Rachel and my senior design project (see next post for details).
I will create a large baby mobile to hang in the gallery. From the mobile my photographs will hang.

Example of Mobile:

I would like the bars to be simple and to have a total of 7 photos hanging from the mobile. So I will need a total of 3 bars which will make space for 6 photos and then I will have one from the middle like the above photo shows.
