I added the Paperclay to my chimney tonight. It will need to dry overnight before I add the mortar, but I am already pleased with how it looks.
I can't wait til it's all done because I am really looking forward to decorating the inside. :) I just I picked up these cute pillows (when HBS had their 50% MMD minis) which match the house. Hopefully tomorrow I'll have some time after work to add the mortar, paint the chimney and finish any touchups before I add the front door (to hinge or not to hinge...that is the question).
