The inside and outside corner moilding pieces beat using a miter and coping saw. You can easily match the SAME dimensions of some of the mouldings and corner pieces. That is essential otherwise the moulding and corner pieces will not line up. Caulk along the ceiling is necessary as with any moulding. I painted the pieces first. Very light and easy to work with.

We used this in my kitchen redo and they it turned out great!

Beautiful style but will have to purchase crown molding before attaching it to corner of wall. May need to reorder 2 more. Style sure makes a statement.

My outside corner moulding is more than I expected. It makes the room look even better.
