Id like to add a shape to a painting on a large canvas Im designing for someone ,but I need ideas on materials to use. The shape will stand outside the edge of the canvas so needs to be durable , so Im thinking card will not be strong enough. I need to be able to cut it out with stanley knife or scalpol attach it and paint it!! Im thinking some kind of wobbly acrylic ( The stuff used for notebooks/folders), but where on earth can I get a huge sheet of it ???????
See I told you it was strange!!
