Everyone loves a tile backsplash. I don’t know why. I guess it beats reynold’s wrap across the back wall of something that might get wet in its ordinary use. Maybe.
For spacers between the tiles, I used popsicle sticks. I once saw a deal on Amazon for a box of like 10,000 popsicle sticks for 15 dollars. I snatched that up. Its chief complaint in the reviews were that the sticks were not guaranteed to be food safe. I sincerely don’t give a shit. For 0.15 cents per stick, I’ll use them for whatever I need them for: glue spreaders, paint mixers, tile spacers, miniature catapults, whatever. I’ll eat food with chopsticks. A lifetime’s supply of dirt cheap popsicle sticks is da bomb!
