I have quite a few old picture frames in my garage and I would like to give them an aged look. The type of look I am after is where you see various layers of paint showing through at random areas (usually on corners and edges). Also looking at getting a crackle effect on a couple of the frames. I have seen youtube videos showing the use of both PVA and water soluble hide glue to get the crackle effect.
Any advice or recommendations would be greatly appreciated.
