I installed new Jeld-Wen windows and saved the old stools. I'm trying to figure out how they should be attached but these windows don't seem to be designed to take a stool -- they are flush with the drywall all around. Referring to the picture, I can butt the stools up to the window wood and have them "floating", supported by trim piece underneath, but that would leave them susceptible to being pulled away from the wall it seems. If I were to lay them on top of the window's existing wood, then the finger catch to lift the window would be blocked. Is there a way to add a stool here besides having it float, or are these just designed to have no stool?
