Definitely match the edge! I am assuming you will have an overhang of stone just below that stainless? I just installed my counter tops and sick that I did pay close enough attention to the edges. I will try and post a pick later - I have 3 different corners - squared, rounded, and extra rounded - within a few feet. The fabricator said the rounded edges were necessary to prevent someone knocking the corners off. At the time, I didn't really picture it so I didn't object. If I could have a "do over", I would do it all squared off. Maybe it wouldn't bother other people, but I will have to always avoid looking directly at that area.

The last thing you want to do is introduce yellow into your kitchen. Sorry, hubby! Those granites are too brassy for 2014! I would suggest Giallo Ornamental Light--not Giallo Ornamental, which is more gold. The crystals are creamy instead of gold, but it does have a little soft gold to work with the cabinets. The garnet inclusions are a deep maroon brown, which will pull the browns from the tile. You will also see some taupe and blue-green-gray. However, it will be a little busy, but that can't be helped if you want granite. I have GOL in my guest bath with dark cherry cabinets, but I held a pine shelf under it to simulate your yellow cabinets, and it looked pretty good. Another granite to try is Colonial Cream or Colonial Gold, but it might be too carmel for your backsplash. If a granite doesn't work, I'd ask myself if it's worthwhile to make such an important, expensive, and long-term decision based on a couple of hundreds of dollars of old tile. You could use a quiet creamy quartz or a quartzite like OOTM posted, but also ask yourself if the age and condition of the cabinets warrants that type of expense. Here's a pic of a Giallo Ornamental Light counter that looks a lot like mine.

I'm limited to granite here, I have a whole range of colors, but I'm focused on black: https://www.google.com.br/search?q=preto+s%C3%A3o+gabriel dark green: https://www.google.com.br/search?q=verde+ubatuba and white: https://www.google.com.br/search?q=branco+itauna+granito The stuff similar to Corian in Brazil is very expensive, much more than I can spare.

wow- I so get this one! This is happening so much down here. I am in south florida, and this seems to be a kind of weird thing thats going on right now- its like real estate agents (or owners) are thinking 'this kitchen is a wreck", (oh- those pink and black formica cabinets that were huge down here in the 50's and the laminated white ones with the wooden strip on the bottom? Not exactly Eames.) So they think, lets plop on a granite counter top to fix this, up the price and sell it all as new! More than a little nuts- right? For goodness sakes- give an allowance for the kitchen to be redone (even gutted) and leave it to the buyer to chose if it fits their energy to redo. !*sigh*! Just as an example- my ex had a condo right on the beach that was amazing until you walked into the kitchen. (Shiny marble floors, floor to ceiling windows, a view of the ocean from the living room and a view from the dining room of cruise ships coming and going- total Hollywood glam.) Then- the Kitchen. The cabinets were plastic- really, truly- hard shiny molded plastic! and- ta da! the countertops were a silky gorgeous polished marble. Nuts! Anyway- I have done this ( moved both marble and granite slabs.) The trick is to find someone who knows how to crate it before its moved at all. Even if its not going anywhere but to the back yard, (or the living room) crating it stabilizes the stone. I have two large pieces that I have moved twice now- one of each. It's expensive, but a good moving company should be able to give you quotes to do it. If you love the stone please dont just rip it out and dump it, it drives me crazy (personal opinion) to think that granite has become a design element that can just be replaced if it doesnt fit a new "look", like on the show "flipping out". If you find that it's prohibitive in terms of cost to do this, then do at least put it on Craigs list. You will be surprised at the number of people who will respond to take it out for you. At the beginning of negotiations, adjust your offer accordingly. The problem is that most of the desirable areas down here are older and the kitchens arent antique-y looking, just really horribly dated. Just because folks spent money on kitchen counter tops doesnt make the kitchen updated. I so get that! Good luck to you on your house search... :D
