Tiling outside corner of wall - quarter round and cove base?
I have an outside corner to deal with when installing a tile wainscot, and I am trying to figure out how to achieve a vintage look on that corner with a line of tile in a different color running down the corner. I'm hoping some of the experienced tile folks that frequent this board can help me. I am using Daltile white subway tile on the wall with black accents. Here are my questions:
1. Can I use black quarter round on the outside corner to make the transition around the corner in the field tile from one wall to the other?
2. If so, what do I do at the base of the corner? Does the quarter round continue all the way down or stop at the top of the cove base (also black)?
3. If the quarter round continues to the floor, do I need a corner piece of the cove base or does the quarter round eliminate the need for it?
I'd really appreciate help on this as I am stumped.
