Trying a 14x14 inch Ambrotype diptych frame today. My workspace is too small to make frames this size easily. The frame is 1x4 pine wood that will be stained Charcoal.
Thought I would share the process. Making a frame is like making an ambrotype, many steps that you improve at with practice.
Note* I got the center divider right on the first try today. Yesterday it took me 8 tries to do the 8x10 diptych frame divider.
