Materials of interest

Wood, rope, clay, pulleys, metal, wire, found objects, tape, rubber bands.

I'm attracted to these sorts of materials and i'm struggling to find the words as to why. It's like who you find yourself attracted to I guess. But I guess words can be attached to that, so i'll try; with words. No help just stating that I like them.
Maybe its the weight that some of them hold, or the imperfections. But sometimes I like to play against their weight turning attention away from heaviness and instead to a lightness of touch or simplistic relationships between materials. Their weight also means that I really have to use my own body when working with them. They hold their own as materials but can have a vulnerability to gravity. I think the word insecurity is important. I like having them have to rely on each others support. For me, the fact that most of them would not be considered "art materials" keeps them moving through possibilities.
