I just made a print on a 11x14 paper. The image itself is centered and about 7x10.

My usual method of presentation is to cut paper flush with the image itself and dry mount it on a museum board, then put an over mat with gap anywhere from 1/2" to 3/4".

With this wide border all around the image, I have an option of not dry mounting but simply over matting with gap between the image and the mat window. I've seen this done before.

How are these two method considered in market place? Not that I'm going to sell this image but I'm curious. Is one better method or more correct method than the other?
