Here is a pic

This would be typical. Is this what you are trying to describe?

Patricia that is what I was thinking but was concerned with all the beautiful photos on Houzz that if I didn't pull everything together just right, it will look plain.

Deborah if you look at the photo I posted, I don't have room for the width of the casing that you posted but yes that is what I was describing.

Just use the size you can, but yes keep it simple. You can always use the size you like in all areas that are not constrained by width and then reduce the size of only those casings where width is an issue.

Yep, thank you
