I'm not sure how I came across this post, I think it was displayed on the right side and I clicked on it being intrigued by the tile making. I was at one time interested in working with papercrete and hypertufa. But after enlisting my brother, who wasn't as enthusiastic, and my niece, who poured cement down my laundry room sink, which original to the house had lasted 70 years, and ruining three blenders, my interest waned. True to form, if I come upon difficulty in a project, I think of it as a sign for me not to continue. And really, after all these years of trying various crafts that result in crap, I should know better. I also should have known better than to ask my brother, who always says it can't be done to any of my unique design ideas. And I should have known better than to ask my niece, who once stayed up all night before having to drive to LA for an art show, cutting mat after mat after measuring once, twice, sometimes ten times, but always coming out with the wrong size. I think we both have math dyslexia. I should video us trying anything crafty to see where we go wrong. I think both of us having ADHD might have something to do with it. Sorry for the backstory and run on sentences. So, I just wanted to see if you continued with your venture. And to say sorry for whatever tragedy occurred to cause you to have to move to Florida. Not that there is anything wrong with Florida, but it isn't Panama. Which is one of my favorite places in the western hemisphere. I hope no one is upset that I brought up a seven year old post.

Have you thought about stainless steel backsplash tiles? https://www.houzz.com/products/4x11-honeycomb-matted-metal-peel-and-stick-backsplash-tile-set-of-3-brushed-st-prvw-vr~100903589. These tiles would look great with your stainless steel appliances.

I don't know what your client has in mind completely. It might be worth asking the client for some inspiration pictures for what she has in mind. I think some glass mosaics might be overpowering for that granite. But there are some glass mosaics that might work as long as they are very plain. Super white glass tile Maybe something like this with a tiny bit of pattern: Silver planks glass tile Or maybe this one which might work with the colour in the counter: glass mosaic - raw silk

OH BOY. I'm sorry I know you must be unraveled, but realistically it looks more like the counters dont go with your kitchen as they are brown tones and everything else looks black white and gray. Why did you leave the granite backsplash up? that would help minimize it a bit I think.. We need to see the whole room.
