I'm building a Victorian playhouse for my daughter. The dimensions of the playhouse is 6' x 6' with a 12/12 gable roof pitch. I'd like to make the roof curve at the eaves by attaching curved tails to the rafter ends. I've searched the web for info on how to do this but can't find anything. Does anybody know a good way or a book or website that would have any info? Also could I use a metal roof or cedar shakes with this process or would I have to use asphalt shingles? I would really appreciate some advice.
