truebluemeandyou:DIY Paper Frame Tutorial and Printable from kreativbuehne. These folded paper frames are quite small - but nice for quotes, postcards, kids’ art, and anything else you want to highlight.
Horizontal, black and white photos are custom framed in vertical mouldings with super long matboards. Just goes to show - don't let the orientation of the art determine where it will and won't fit. Anything's possible with custom framing!
