inner panel how to make it neat in outer/inner corner

[JanneSjo]

I am going to install panels like this and I'm wondering how to make the corners look nice.

I have seen someone use a square trim, slightly wider than the panel, in the inner corners so that the panel goes against the trim on both walls.

But maybe it looks better to just have the panels meet each other?

How do you make it look nice on an outer corner?

It's a matter of taste, I think it's nice with moldings, if you rabbet the moldings you can let the panel go under the molding and it will not be as visible a joint. You can also put a molding on outer corners in the same way.
Square molding is an option, you can of course also have other shapes, concave molding or others.

I read an assembly guide for wall paneling somewhere... anyway. It stated that it was important to have a margin for movement due to changes in humidity over the seasons and the use of the home. If you then place a square molding in the corner, it might cause problems? I'm unsure how much it actually moves. But if you do as thomasx suggests, and make a rabbet on the square molding, insert the panel behind it and leave a gap (that won't be visible afterward) it should work...

Or, are you going to install the panel horizontally or vertically?

horizontal panel pre-painted

will soon be installing it but will put up 3 doors first.

was considering placing the moldings directly against each other without a corner molding in the inner corner - tested it and it looked okay - however, the wall is not plumb.

wondering how much moisture movement affects it.

in the room where I am sitting, there is horizontal paneling with square molding, I just noticed - you become quite blind to what's seen every day... here, the panel sits flush so maybe it's not an issue

I also have a free side of a wardrobe where I need to end with a molding "against the air"
