Upgrading the Dining Room Window

When we decided to make our dining room more formal, we knew the molding would be a major part of it. The old window casing just wasn't anything to get excited about:

I wanted something bigger with a bit more polish. Like these:

To make the casing wider, we needed a longer window sill to support it. I measured the length of the window, added the width of the casing (4.5 inches) times two, and added another inch on each side for over hang.

And luckily, the side casing seemed to fit just right. 

The frieze (that big wide board on top) needed to be the length of the window + width of the side casing times two. The apron (the thing under the sill) needed the be the same length as that, but then cut at a subtle 10 degree angle. 

Originally I had ordered a 2.5 inch solid crown to go at the top, but it was too heavy and we were worried that it would put a strain on the other pieces and likely the caulk that will hold it all together. I picked up a regular crown that was basically the same to replace it. 

Viola! Our completed window casing.
