what to do when you can't buy it?

You call me.
Here a local well established builder needed some custom window casings to match the profile of the rest of the trim in the house cut to the radius of three radius top windows that he has installed.

He needed the trim and the extension jambs for the tops of these windows.

Here you can see the exact match to the target piece I had to work from. He should have no problem  making these radius pieces match up with the standard trim he is using.
