Camping Party!

I need your ideas!

I've got two weeks until the big three person 30th birthday party!  I think I've got all my supplies for the manzanita branch centerpieces I'm making, but I wanted to get your opinions on a couple of things. 

The branches


I went with natural and I'm going to spray paint them white.  There is a lot of brick in the room and I think white will really pop.

The containers?


This is one thing I need your opinion on.  Is this container ok for this?  It is made of paper mache and 10 inches in diameter.  I'm just wondering if it will look ok.  It's not a formal party, but these looked a tad too informal.  What do you think?

The crystals


I also have gold and silver 30s to hang from the branches.  Another question I have is what type of filler to use around the base of the branch?  What would look good with white branches, crystals and gold and silver?  Do you think something like moss or rocks would go?  Or should I use more crystals?  Because the branch is not natural looking being white and shiny, I didn't know if I should use a natural filler.

Thanks so much for your help.  I look forward to hearing your ideas!
