Words Have Limits..

I started this project with the theme 'Isolation' ....after having a chat with my tutor I realised the word 'Isolation' has limits, it is only a word after all, it cannot fully define the feeling of isolation. Isolation then lead me to themes such as restraining the body, confinement, being trapped, however, again these are all only words...I am now trying to turn these words into Art....what to they look like? Feel like? smell like? Sound like? What colours to they conjure up?What effects do they have on materials? What materials are related to these concepts? I think the epiphany I have had is that words should not restrict my art...not everything I create has to be defined by words.......art should not always have a write up next to it telling the audience what they are experiencing the art should 'speak for itself' ;P
