I just bought acrylic crown molding to install in my home. The problem is that I do not have the smallest clue of how to make the cuts. I have read that you need to make 3 cuts in order to obtain a decent fit!! (one for length and two 45° cuts) Is there any other way to achieve this without that many cuts? ( all I have is a miter box and do not have experience working with an electric saw). Any help will be deeply appreciated!!!!
