My shooting range has started to collect the signs for a few projects. We are going to use them as target backing and use them to block off areas of our baffling to refine our down range air flow.

SOAS gets a new life as something useful!

Target backing sounds like an excellent reuse of corrugated plastic signs. Good idea.

I use the CP signs when making picture frames. The go behind the photo with a layer of paper between. I take them to the Air Force base hobby shop for others to use.
