Hi, I am new to garden web, so thank you in advance for your help. We want to add a window trim to the interior windows in our family room. The only problem we are having is that the sills only extend about 1.5 inches on either side of the window. So, if we were to just add the casing it would have to be pretty narrow. Do you think this would look funny? Or should I just hire someone and have them also redo the window sills ( husband isnt willing to do that part since he is afraid of harming the walls when he takes the existing out).
