????DIY????

Has anyone ever done a centerpiece with branches that spread out more...most of the ones I've seen, the branches are pretty much straight up.
I want it to look more like a mini oak tree, without the leaves. Also, is there any way to put little lites in the branches? Kinda like christmas lites only, battery operated so they don't have to be plugged in.

Any advice would be much appreciated.

TIA
