Well, I've been putting it off and off, and now is the moment of truth.. It's time to put the backdrop up. It'll be hooked directly to the wall (i.e. doesn't need to have much structural strength itself), and go from layout to ceiling. I'm just not sure what to use: Hardboard... Joints tend to crack open, and too stiff to bend to create "radiused" corner, which I'd like. Drywall. Easier to hide joints. Definitely not bendy in the corners. Paneling, a/k/a thin hardboard. The only thing I found at Home Depot with enough "give" to work around corners was the absolute cheapest "plain white" paneling they had. Homasote? Never actually seen the stuff. I hear tell they sell it at a building supply place about an hour away... Other?????
