I have a home built in 1949. All the windows were replaced a few years ago. Now i and working on updating the Trim, but noticed that the Sill are an Odd size. the Rounded ends are only about 7/8" long at each end pass the main window frame. The Trim on them now is only 7/8" Flat Rounds (edges). If i replace the Trim with a 2" or 3" trim, i would have to notch them at the bottom then meter the corners. Any suggestions as to how to trim around these windows? (i tried to upload a picture)
