Help me with Crown molding design

[smorgasbord]

So, my Murphy Bed build is just about complete. I want to put a crown molding on top since just having the panels end doesn't look that nice. Here's a photo of a crown mock-up I built out of scrap:

This is what the visible cross-section looks like:

Thoughts and suggestions welcome.

Personally I'd run a cove bit along the two faces you have the angle spec running along so they're not flat.

I'm pretty obsessed with keeping the Shaker flat aesthetic going, though, so not looking to add curves. Originally had designed a Wright prairie-style crown, but that stuck out too far from the sides when I made the mock-up. And, didn't want a more typical Craftsman vertical crown since I thought that worked best with doors and windows (where I do have that). So, trying to find the right horizontal/vertical proportion and then a set of double angles, but not sure about the angles and which should be greater/lesser, etc.

That makes sense if you're wanting a Shaker look!

Maybe making the bottom part or the top part slightly narrower so there's a larger ratio between the two parts, instead of being almost the exact same width? I'm thinking the Golden Mean ratio.

That sounds like a good idea. Which way would you recommend?

Here's the cross section with some dimensions:

You could increase the top or bottom section, reducing the other, I think myself I think the bottom part larger is slightly more aesthetically pleasing to me, or you could go a variant of something like the 3rd pic I hastily did (apologies for crude quality), just as a suggestion anyway.

I tend to agonise over these sorts of design aspects! ;-)

I would try for something that made installation simple.  I have always found crown moldings (at the ceiling) a challenge.  (I can show photos to prove the point. [big grin] [eek])

I googled: Crown moldings, Shaker style, profiles [images] and you can pick and choose.  I personally, would choose a symmetrical profile, so that there is no risk of installing the molding upside down.

I would try for something that made installation simple.  I have always found crown moldings (at the ceiling) a challenge.

This is just the top of the Murphy Bed cabinet - nothing will touch the ceiling (which is high and angled). Which is why my design was based on things like Mission clocks and other stand-alone items.

This is the door top molding that I designed and built for the same room (actually all the rooms in the house):

My wife wanted a variant of that, but I felt that while it works well on door and window frames against a wall, since the bed cabinet comes out from the wall I should have something that "tops" itself more.

But, maybe she was right after all.

Still noodling with [member=75933]luvmytoolz[/member] variations....

It might not be easy to see, but I made the molding return upwards towards the ceiling over the tiled area, and back towards the wall just a few inches away. 

The tile work meant that the moldings did not match up.

I did not spot the inconsistencies until I started painting.

I’m not sure what type of crown molding would have prevented this.

The bathroom was completed a few years back.  No one seems to notice.

I would note that the “builders’ pack” of 10 sticks at Lowe’s was not the exact profile of the individual pieces.  I bought a single stick and it would not have worked.  I don’t tell anyone about this error.  It is my dark secret.

Here's my latest design - will head into the shop later today to build in scrap:

Here's the finished crown - thanks for the help!

I'll start a separate thread for the complete build later today or tomorrow.

Beautiful work! Love that colour and the grain!
