Can anybody give me some tips on how to do this safely and cost effectively. I am knew to this and dont want to make mistakes which may be avoidable
I paint on loose canvas so they can be rolled into a cardboard tube and sent anywhere cheaply and safely.
If the canvases are the same size you can buy (or make) clips that hold them face to face, with a small gap between. Search for canvas clips. eg. http://www.dickblick.com/products/holbein-canvas-carrier-clips/
You can get wet canvass carrier in cardboard from Cheap Joe called Handy Porters. Here is the linkhttp://www.cheapjoes.com/guerrilla-painter-handy-porter-box-12-x-16.html
