I'm working on upgrading the kitchen and want to extend the backsplash of 1x1 white 'dimpled'tiles to the wall area between the cabinets. Unfortunately, I've found no match for these tiles which we installed around the stove back in the late '60s, and which are still in excellent condition. Is there any source for matching old tile? I have a similar problem on white floor tiles in the bathroom which are cracked. They only date to the 90's.
