We had a C shaped counter to tile with a stove in the middle of one wall, and a window in another so that's where we began so when you look at it, those areas have whole tiles, and the area behind the stove under the old hood is even. We ended up with partial tiles at the corners which doesn't matter much as you can't see them the way you see the other areas. The ends have some partial tiles, but that's going to happen with a subway tile configuration.

Go to youtube and search for videos on how to do it.
