I've recently been running some workshops for young people that have involved using mud. The preparation of the space (not by me) has been reminiscent of an alien autopsy lab ..... the floors and tables covered with thick plastic sheeting to 'protect' the room. At the end of each session I've bagged up the slightly soiled plastic sheeting with thoughts of sculptural pieces. Having brought them into the studio I've added dirt to them and began working with it on a large scale, something I don't often have the opportunity to do.
I always love a peek into fellow artists studios, seeing work in progress and ideas being played with.
