The builders did not put any casing around our windows and we would like to put some up. The window ends of the sill (or stool) extends only 3" beyond the window. This is standard for the builder grade 2 1/4" window casing trim.
However, we really would like to put in a wider Craftsman style window casing that would extend beyond the existing window sill (stool). We could stand the sill to be flush with the casing, but that would require 2 3/4" case moulding (which does not exist as a standard size). Could we cut off the ends of the sill to be flush with the inside of the window? OR... could the wider casing just wrap around the shorter sill? Neither of these ideas follow the standard rules of trimming out a window.
So the question is... Is there a way to work around this problem without having to cut and install new window sills throughout the house?
What is the easiest solution?
