Carrie at her creative Dittle Dattle blog has posted several DIY tutorials, including framing projects for nautical custom frames, a frame-within-a-frame and a (higher skill level) shadow box frame. She also created a great home project wall display using square white frames. Her clear instructions and running commentary are delightful, as well.
Pretty matted frame-within-a-frame instructions can be found at Dittle Dattle's Framing Frame
Instructions for these nautical frames using pallets or rough-sawn lumber, boards, nut mounted glass, and chalk paint are available at Nautical Custom DIY Frames
