I am an owner builder that needs help on how to trim out a bay and bow window.  I have a large four segment bow window under the porch that needs ext. trim.  I also have a small three segment bay window in my kitchen that I need to trim the outside on.  Both windows are finished on the inside.  I think I can work my way through them once I get started,  however I would like to know if there are any books or magazine articles dealing with this.  Both windows are Anderson casements with crank outs.  The bay window is about 4 feet wide and ext. of the house is brick.  The bay is about 6 feet wide and the ext. of the house is not yet done but will be cedar siding.  Any help you folks can provide would be appreciated.
