Shoe Tree?

So I guess the first thing I should do is explain what I mean by a shoe tree. I do not mean an ugly wire thing you use to hang shoes on in your wardrobe at home, far from it. I plan to construct a tree made from shoes. I will be using worn shoes (not my own) but they will all be female shoes. I will most likely not be including high heels as i do not wear them myself. The shoes represent to me an embodiment of persona and of journey, of being grounded and of past and future.
The kind of tree I have in mind to construct is like a Morten Bay Fig tree but this will all depend on process and how I go about the construction.
Why a shoe tree? I want to make a tree because of the symbolism of growth, new life and cycles of life (It has been pointed out to me that the type of tree I have chosen is a deciduous tree which goes through cycles where it looks dead and then alive) I feel this is a wonderful metaphor for what I want to say with this work.
So what do i want to say with this work ... well that is what this blog is all about - developing my concept. Thus far my concept has a core of journey, growth, paths and choice.
