You will not lose any of your image as uploaded to the website when we wrap it around the edge of the stretcher frame. For the black and white edge, this is obviously not a concern. For the mirror image, we simply mirror the edges of your picture to give us enough material to stretch the canvas around the wooden frame. This gives the print a beautiful appearance and it is almost unnoticeable to the naked eye that the edges have been mirrored. This ensures there is canvas on the side of your prints and that the wooden frame and staples are always hidden from view.
