Backsplash - run it down to counter, don't put in 4" counter extension slab. I've always wanted cabinets with glass fronts at the top, to display my pretty stuff, but keep them from getting all dusty or broken. I'd also add little lights in there. PS: This is the most repinned pin I've ever had by far.
Farmhouse sink, and a counter top that flows into the backsplash - Very pretty!
