Someone may have already suggested this, but here goes:
Take some of your trim to a picture frame shop and ask them to make you a 1 foot by 1 foot frame. Let THEM go nuts determining how to make it look good. However, ask them to just tape the frame on both sides, not any type of permanent fastening....
Bring it home, use the other fine suggestions here, and match the picture frame pattern for your particular molding. Thus, you have a template (Shades of S. Frederick and his jigs!) to use in layout before you cut...
