Acrylic on canvas with draped paper.
The effect of soaking the paper in medium lends it a fabric consistency and allows it to be draped in quite a natural sense. Its instability is something else though and many a disaster has often been the result! Though once it is in place and it drys, it is rock hard and completley stable. I love the effect and have used it quite a lot.
In fact I just remembered, for those who are football fans, this was actually displayed in the directors dining room at Old Trafford, the home of Manchester United.
