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!
Invest in a simple mat cutter and the world of framing is at your fingertips. Cutting mats is easy, inexpensive, and takes your artwork to a new level. It looks custom, even if you buy a readymade frame from a store.
