Does anyone know a good website that illustrates how to cut miters on inside corner trim for your ceiling?

Question

I am working with inside corner trim,not crown mold. I am having a heck of a time figuring out how to cut the miters in the corners because the trim sits on an angle, not flat.

Answer 1

DIY talks you through it:

Dewalt shows you what the cuts should look like:

I know you said "not crown molding", but frequently the method is the same.

Or... it could be similar to installing baseboard trim:

Answer 2

If you are using a miter saw place molding as if were on your wall and then cut at a 45 degree angle

Answer 3

DIY stores sell a mitre just for this task. A worthy and less expensive option. Even a couple of degrees out will mess up the job otherwise!
