Match the other trim used in the space! :-)

Use a L bead. It gives a nice clean edge.

If you use trim, what will it look like where the wood stops. Any applied trim needs something to dead end into.

It depends on whether the drywall butts up against the wood or the wood butts up against the drywall and how much of a gap you are trying to cover n either case.

I'd use the blue pine trim flat on the ceiling from what I see in that photo.

Thank you for making use of the blue pine. Lodgepole blue pine in the U.S. and Canada is caused by the Mountain Pine Beetle and the fungus is carries. The fungus stains the wood and the bettles and larva kill the tree. Naturally occuring and in the past controlled by seasonal cold temperatures. Since the early 2000's and warmer than normal winters, Colorado has lost 70% of lodgepole acreage and in Canada it will take 44 million acres. Lost meaning the trees are standing, but dead. Climate change may have contributed to the size and severity of the outbreak, and may affect the capability of northern forests to remove greenhouse gas from the atmosphere. It poses a major fire threat. It's not the most easily commercially accessed for cut and has a relatively small diameter for mill.

Your ceiling is gorgeous! I know you were worried about it, but it truly is something special. Gives me ideas about our future house..

I would match the trim used in the rest of the space. Looking forward to seeing the house completed! It sounds like it’s been quite the adventure.

runnem, I guess adventure is one word for it !
Thank you so much for your input! I will post pictures down the road. Glad I gave you some ideas for your future .

Congratulations on useing pine beetle wood! It is beautiful. I woul use the smallest size pine trim you can do as to not take away from the long beautiful lines.

sandramartin, smallest size Pine trim? What size are you thinking? they can cut it any size.

We have knotty pine ceilings in our place. Whoever installed it (probably back in the 60's or 70's) used pine trim stained to match as trim pieces.

Here's a photo from before we gutted and re-drywalled this room. It's obviously not totally comparable to your space, much smaller home and the ceiling isn't even 8'. :), but you can see wood ceiling + matching wood trim if to helps to visualize.

For my space I'm not wild about the pine trim with the pine ceiling and I've been thinking about painting it to match the wall color in each room it's in. That way the gap is covered but there's not this additional deco element competing with the ceiling.

Small rectilinear piece painted the wall color

Matt, do you mean, to cover the seam? like a 1-inch wide strip painted the wall color or...?

Nicole, that does help me to visualize, and I like your idea of painting your trim the color of the wall in each room. you would still have the dimension of the trim, but not extra deco like you said.

tatts, do you mean you would cover the gap / seam with a flat piece of the blue as the trim like the trim on the rest of the ceiling?

What do you all think about the trim around the stationary windows at the top? The Builder wants to use the blue wood as trim but again, that's just a lot more blue. Would it look nice if I used the same colonial trim that we are trimming our windows and doors with up there around those windows? I could paint the trim around the windows the alabaster color of the walls or the white trim color that we're painting the window and door trim with ("Extra White"). So many decisions!

Keep the blue on the ceiling. Use same trim as elsewhere around windows.

Here is how ours was done. Ceiling is pine. They used pine to trim where ceiling meets sheetrock.

Exactly Vinmarks! Perfect visual. Do what it takes to cover the gap but keep it inconspicuous. Either the tiny trim on the wood the same as the wood, or on the Sheetrock painted the same as the Sheetrock.

Nice ceiling! I would use cove molding.

PPF, that's what I wanted to do. thank you for confirmation. I just don't want any blue on that wall, or any more in the room.

What vinmarks said and showed in her photo.

Teri, about 8 years ago we did reclaimed wood on our ceiling. we used the same wood as border pieces all around the ceiling (since where it meets the wall is rarely plumb/even). could you do something like that?

Or just use regular trim and paint it to match your walls

Beth, thank you for your input. We did do that for the rest of the room but I didn't want to put more blue trim on this last wall. There's so much blue wood in the house, I wanted to leave this wall just white. so I think I will do your second suggestion of painting the trim the white color of the rest of the walls.

Well...there's been a lot of good commentary in regards to the question of what sort of trim to use at the intersection of the wall and the ceiling.

I think the issue comes down to this:

There's going to be a large amount of trim used around the upper windows very close to the intersection of the wall and the ceiling. In addition, there's going to be a lot more trim used around the lower windows and door. Said differently, the end wall, with all the windows and door, is going to have a lot of visible trim.

The same applies to the side walls: windows, with trim, are close to the intersection of the wall and ceiling.

Thus...does one want to see different and competing trim sizes and colors? Does one want the trim to be visually similar and consistent? In other words, does one want visual contrast and the trim to be very noticable? Or does one want visual harmony and as little attention given to the trim as possible, given the size and type of trim used?

This is why I recommended to make all the trim the same everywhere. Your milage may vary...but understand the effect of your choice.

Virgil, while I subscribe to harmony with trim mostly. In this situation, my thought on the ceiling is that it is a stand alone piece. To trim it with a small piece of the same wood frames it like the piece of art it is. I have changed my mind on trimming it to match the walls as an option after seeing Beth’s, but I remain convinced that it should be very small and minimal given the color. That ceiling is so gorgeous, and so is yours Beth!

Sandra, you make a good point.

But the thing about architectural design is that one must consider the bigger, holistic picture and try to achieve a harmonious solution, integrating all the elements involved.

Installing a small trim piece to match the ceiling at all of the intersections of ceiling and wall is one approach. But it increases the amount of that unique material, brings it down from the ceiling and onto the wall, and it increases the different trim finishes on all the walls.

I wouldn't do it, but your mileage obviously varies. I agree that it's another approach. Hopefully, these different views will give the OP some good alternatives to consider! :-)

Terri, the L bead suggestion is a good one to consider as well. Take minute and youtube L bead drywall finish and you can see that it will fill the gap and you won’t need any trim at all. That would give it a clean look and you can always trim later should you change your mind.

I third the suggestion to use L bead. Gives it a nice clean finish and is great to use anywhere drywall meets a dissimilar material...wood, stone, brick, block, etc.
