I've been making a 3d tree to go with the pictures, as an interactive part of the exhibition. The tree is made from my Nanna's old extension lead wrapped in thread. Of course her extension lead is the same as anyone else's extension lead, so when I spoke to tutor Jonny about it, he wanted to know the significance and asked whether my nanna wanted to be an electrician, which she didn't. I've justified it by the fact that you can't tell it's an extension lead now it's finished. After all, no one's questioning whether the paper or paints I use for my final pictures belonged to her (which of course it didn't). I just used it because it was a good choice of medium to get the effect I wanted. In fact I've just convinced myself that it's perfectly reasonable!
