As TSG said two of the options are to incorporate the transition, or hide it. It is hard to know which will work best in your space without knowing how big the crown will be and what style you have in mind, etc. Here are some examples of incorporating the window trim with the crown: [[(https://www.houzz.com/photos/traditional-bathroom-traditional-bathroom-new-york-phvw-vp~1034813) [Traditional Bathroom[(https://www.houzz.com/photos/traditional-bathroom-ideas-phbr1-bp~t_712~s_2107) by Stamford Architects & Designers Sound Beach Partners LLC [[(https://www.houzz.com/photos/shingle-style-home-in-hanover-nh-victorian-bathroom-burlington-phvw-vp~106093) [Traditional Bathroom[(https://www.houzz.com/photos/traditional-bathroom-ideas-phbr1-bp~t_712~s_2107) by Norwich Architects & Designers Smith & Vansant Architects PC [[(https://www.houzz.com/photos/chestnut-street-bathroom-traditional-bathroom-boston-phvw-vp~96002) [Traditional Bathroom[(https://www.houzz.com/photos/traditional-bathroom-ideas-phbr1-bp~t_712~s_2107) by Boston Kitchen & Bath Designers Venegas and Company [[(https://www.houzz.com/photos/case-design-remodeling-inc-contemporary-bathroom-dc-metro-phvw-vp~87107) [Contemporary Bathroom[(https://www.houzz.com/photos/contemporary-bathroom-ideas-phbr1-bp~t_712~s_2103) by Bethesda Design-build Firms Case Design/Remodeling, Inc.

When you signed off on the cabinet order, was the order placed right away or did it wait until the molding price came in? I bet you are being penalized for placing a separate small order and they may have a minimum shipping charge that you would not have had to pay if the molding had been ordered at the same time. Do not mention it until you get an answer, but if yes, it is more for that reason, you should let them know you expect they will take care of this without penalty to you and speak with a manager if necessary. They should not have placed your order until it was complete if it would cost you more to do wo without discussing it with you. If they didn't, you should not have to abosrb the cost. If you are still within the time when you can cancel the entire order with minimal/no loss, you might nicely inquire if that is possible while you work this out, and then place the order again with everything included. Before you say anyththing else you might want inquire if this is the case. The fact that the labor for the molding was included in the original contract clearly indicates that they were aware that you wanted it. And, yes, I think molding makes a huge difference in the finished look of the kitchen even if it is a very simple molding. The one exception might be a galley type kitchen or a contemporary style. JMHO. Unless DH is exceptional, most men don't place anywhere near as much importance on aesthetics as you would, but chances are when you go to sell, the molding will pay for itself. Sue

Correct. The bookcase would not have its own molding at the top. In my mind, the problem with your carpenter's plan is that 1) the difference in appearance of the two moldings would look odd, and 2) there isn't a good way to start the crown molding on the right hand side of the bookcase because the bookcase molding flairs out. There is no good way to connect them.

You use the kitchen crown around the whole room. Or you use the room crown on the cabinets. No cheesy plinth blocks and 2 different crowns.
