Both seemed a bit plain, so I attached some brass appliques using E6000.
Each frame was dry brushed with white paint.
On the larger frame I turned the frame sideways and cut two lengths of baling wire a bit longer than the width of the opening. I equally spaced the wire in the opening and stapled the ends to the back of the frame. Hmm…I guess I didn’t grab a photo of attaching the baling wire to the back, but I bet you can use your imagination.
