Personally...and I'm a real frugal person and everything I can myself...but personally, I think I'd hire it done and sit around watching them drinking endless cups of Chamomile tea. I don't have the stamina to undertake something like that.
Steve and I redid our entire shop interior from the insulation and sheetrocking and painting and trim. We hung a suspended ceiling and everything. So I don't wimp out easily...but I think I would with painted on wallpaper!
I think that may be the best plan...it's something that would be relatively simple with the right equipment, but VERY messy and aggravating with what I would most likely have to work with. I'll have my car paid off by January or so (
), so I can start saving up for projects like that!
