Print any picture you want, spray paint a piece of wood black, cut the picture to match size. Mod Podge wood & lay picture on top. Once dry, use sandpaper to rough up the edges & Mod Podge over the picture. Paint eye hooks & use pretty ribbon as a hanger.
This is more just an idea for something you guys can keep your eyes out for at garage sales (old pie tins). I would really like to have a wall like this (old pie tins as frames) but have yet to run into any tins.
