Hi! I'm struggling with how to start/end our kitchen backsplash on this wall. There really isn't much symmetry nor any natural breaks for the tile to end. There will be a stove in the middle, and a microwave/range above so the backspash is definitely needed. I can provide more pics if needed! Thank you in advance for your advice!!

Look at the Chloe tiles. They’re simple, organic and have lovely texture. You can do so much with the texture of the tile and the way you lay it out. Pick a simple tile that you like and you can do brick pattern Straight set Or lay it vertical Herringbone .... So many options!! Kitchen looks amazing already!!

The top end choice would be to use a beautifully figured piece of alexandrite slab as the backsplash and focal point. It depends on your layout and sight lines. Whether the alexandrite is polished or honed and lighting come into play. Tile choices require taking your component samples to some tile stores and seeing what you like. Patterns like subway, herringbone, stacked, chevron, etc. depend on your interior decor style. Get samples to compare in your home lighting. And compare grout. Urethane and epoxy grout resist staining for lighter colors. Post pictures of the options for feedback.
