This is a commission I painted for a client in Australia, it is a 30x30 size. I sent it to her un-stretched, rolled in a tube; this way she paid only 50usd for shipping (to send something this size, stretched onto a frame to Australia from the US would cost many hundreds of dollars.) Her handy boyfriend attached the canvas to a frame himself!
I painted lots of extra inches around the edges, so it was easy to get a clean look, with the edges looking like an extension of the painting, wrapping around to the back; easy! The paint is not harmed at all by doing this. Isn't this the cutest office? This is where magic happens.
