I think in this case a metal Schluter system trim might be best so you don't have rough exposed edges. Unless this particular tile also has matching pencil liner, don't do it. You'll never match the whites.

I can't tell if your cupboard is aligned so you can go straight up from your raised backsplash level using either a Schluter edge or matching pencil. Looking at your tile, I'd also use a white Schluter with it.

We used a brushed metal (aluminum, I think) Schluter trim when we tiled. I love it.

abby, nice example. We used a pencil edge, so I'll post it. (Also, pie brag.)
