Corrugated Plastic Backing

[GunLvrNLearner]

With target stands like Birchwood Casey,Caldwell and others they come with the backing...

Where can i find cheap replacement corrugated plastic backing?

Thanks

Everywhere come election time. I usually stock up after elections are over.

Maybe in hardware stores, around sign boards.

Craft stores, in around the foamcore boards.

Hey, some of those old school projects actually did teach me something!
