I am looking for large cove moulding. I can't find any in stores that is over 3/4 inch. Everyone only has more ornate crown moulding. My builder is putting up a flat board up to the ceiling and is going to finish with a large cove moulding. I'm looking online, but am not sure how big to get. It's so difficult when I have no samples, and have no idea what sizes will look ok! I did go get some crown samples to look at sizes. Should I just go by this? Any opinions? Anyone have any good sources online?
