Can't help with the photoshop.....but have to say I love the tile you chose. I 'wouldn't' go up and over the window. I think it will draw your eye to the window, and don't think that's what you want. Having tile up there will also make hanging WT's a real pain! If it were my kitchen, I'd trim out the window with wood molding and then have the backsplash butt up to the sides of it.

I have a marble slab b-splash behind my range. It's Vermont Danby, and it's very white. My marble is sealed with Porous Plus 511, and I have no problems at all with staining on my b-splash, even when tomato sauce, etc. splatters and I don't notice it/wipe it until the next day. I may be able to find some small oil marks that have been neglected, if I look very closely, but it basically still looks like the day it was installed, about 14 mos. ago. I probably have etches from those types of splashes, but IMO, etches are hard to see on a b-splash unless the light is exactly right. (My counters, on the other hand, are full of very visible etches!) I also have a friend with a carrara tile b-splash, she has a large family and does a lot of cooking. It's been about 3 years, and her b-splash has held up beautifully, and still looks great.

Deb: $125 per foot!!! Oh my! That's almost twice as much as I paid (prefabricated, I paid $40.38/sq ft). I did some testing and while it did MUCH better than the marble, there was some staining (not etching) on my pre-sealed sample when I had a few food stains that sat for 24+ hrs. My fabricator claims that sealing the granite should take care of the light staining that I saw, so I am trusting him. I actually don't care that much if I have some "lived in" looked. I have lived with marble so I know what that feels like, I am just hoping to defer some of that permanent etching that we had. If you have white cabinets and a wood island, I might actually think about the Caesarstone if you can't find the white princess. I was pleasantly surprised to see a showroom by Christopher Peacock that was done in the Caesarstone that looks like marble and it was REALLY pretty. I would never have believed it unless I saw it myself. Wish I could have taken pics but they wouldn't let me! The other option I love is concrete! Might be too un-traditional for your style, but I really like the counters in my friend's house and they are very light gray--and very easy to take of! Despite what some people say, she has never had a staining problem. They have a gorgeous patina that is really pretty and I love them with the white counters. Not her kitchen, but similar--look how pretty the concrete is! From Menlo Farmhouse

Joseph Corlett, LLC; are you familiar with Cambria Bentley? I used that to do exactly what you’re talking about, and there was plenty of slab to cut the countertop and backsplash from with many inches left on either end. The countertop should have been shifted to the left of the backsplash and then cut to match as it laid on top. It wasn’t. I feel like this is pretty elementary; however I guess I may be wrong. Can you look at this and tell me your opinion? (These pics of the backsplash bleeding into the countertop are not really great or from far enough away to get the whole idea, but you can tell it doesn’t line up). Thanks.
