DIY Picture Frame: Get the Rustic Weathered Pallet Look
These picture frames look like they are made from reclaimed wood pallets but are really made from cheap white wood that's stained to look old and weathered! There's a great video tutorial that shows you how simple (and inexpensive) they are to make!
I'm not big on gallery walls, but I like this idea. Make it a small smattering over a hall table/entryway bench, and fill in spaces with small items/letters instead of just a bunch of similarly-sized frames.
