It's just a whole lot of wrapping strips of cut fabric around all the branches and hot glueing them down.
And here you go. 16 glue gun burns and blisters later. She's all done!
My husband actually really likes this branch. He thinks it looks like some sort of sea creature. I don't know, different strokes for different fokes I guess. I could see something like this being cute in a childs room, or even hanging over a crib like a mobile, with all sorts of interesting baby things hanging from it.
