My Gallery is about 12" sq. I have used garden square trellis painted white mounted on the walls. Makes frame hanging easy as framed prints can be moved and aligned very easily.
Its the displaying of unmounted prints that is the problem. Waist high 'vinyl bins' is probably the best way. I've tried old wooden vegtable boxes painted white but they need alot of prints in them to stop prints from getting dmaged.
thanks again for your inputs.
