I have a very old traditional style fireplace shaped out of plaster. I've remodeled the rest of the house for a more modern style, so I want the fireplace to match. I thinking something with clean straight lines, so my idea was simply to wrap the existing fireplace with drywall to cover the detailing that made the fireplace look so traditional, and mud it to give it it's straight lines. However, i'm not sure if screwing drywall into plaster is a good idea. Any ideas?
