Have you seen this? Sounds like just what you are talking about. Sarah Susanka is one of my absolute favorite architects.

I was looking for something little different for the house I just completed. I was replacing the doors and using a simple craftsman type door and shaker cabinets. I used an idea from a 1920's house I owned which was back banding a 1X4 and then I just used plain 1x4's for the base.

I am moving and currently renovating the new house. I am using the craftsman doors again but found 1x4's I used in the last house to be a little too heavy looking once I got them all in so I ordered all the moldings for the new house from a lumber yard and went with a similar look but the backband is built into the molding and the base is thinner. I chose 420 for my door and window casings and 433LM for my base from the attached catalogue. Both very simple but different from what you get at the big box stores and see in most houses. No pictures to show, I have 1000 sq ft in the garage waiting to be installed. I negotiated the price and got it for less than I would have paid at the big box store.
