I would like to address this to all of the replys above. There is not any reason that making a perfect fitting joint in any trim/crown should be a trial and error or even a coped joint. Most of the books on trim work still use the coped method. There is one book however that actually tells the beginner (and the pro) excatly how to make the perfect cut for any corner including installing crown on a sloped ceiling. Also, free online tech support is available from the book author. Visit us at
