Porthole Shadowbox Frames
Punch a clean 5-inch circle into thin-gauge steel sheet to create a round ‘window’ in a square or rectangular frame. Back it with acrylic and a photo or pressed botanicals for an industrial porthole shadowbox; the 5-inch slug can be polished and used as a magnetic photo plate for a second piece.
