Flat Baseboard Stock

[chefwong]

What is the rule of them when doing flat baseboard stock in a modern theme

Doors are caseless with a 1/2x1/4 reveal to them.

Does the exposed ends get a return or not ?
Corners don't seem to be mitered but just butt into each other.

My favorite detail with caseless doors is to run the baseboard flush to the sheetrock, with a 3/16" x 3/16" rabbet at the top of the base. That way the base can butt into the door jamb.

When I've done this, I've butted inside corners, miter outside corners. For the "self return" ends, I would ease the edges with round over or chamfer bit and sand the endgrain down smooth so it is closed and won't end up rough after paint or finish. I wouldn't bother with an actual mitered return.

I'm not too familiar with caseless doors, however.
