What we do to get the most from our wall space is to rotate work. As my wife is an artist, there are new works to hang and older works to retire and/or sell. My own stuff rarely lasts more than two or three months on a wall. The photographs we've purchased, though, stay up for good.
I work like jovo, my stuff gets rotated out of one frame, but the purchased/traded images have stayed up. Just hoping to have enough good work over the next year to be happy with a rotation of 2 images.
Let's see what I've got in the magic trash can for Mateo!
