Anybody can do a regular crown molding inside and outside 90 degree angles. How about doing fancy corners like this one, it is so simple but the first thing we got to do, we are going to go back in time to your high school geometry class. You should have paid attention.

Most of those inside and outside corners are 90 degrees, divide 90 by 2 that gives you 45 degrees. So that is what I did. A simple 45 cut makes that perfect 90. Okay same 90-degree angle but this time, we have got four cuts because we are adding a third piece of trim. So, take 90, divide it by 4, what does it give you? 22 and a half degrees, how hard is that? I have already made one cut here at 22 and a half degrees to make the inside corner triangle. So, now I just have to make the second cut.

Here is an outside corner and an inside corner up on the wall and remember to make all this happen, it was just 22 and a half degree cuts and look, here are the inside and outside little corner pieces that I made to make it happen. It is really, really simple.
