pinterest pin. I found the tiles at our local Home Depot, 10 natural tumbled stone tiles for right around $3.00. I used Stayzon Ink and CTMH alphabet stamps. Than I masked over the monogram with a circle punched from the sticky end of a post it note and stamped with a large background stamp. After the ink dried I sprayed....and sprayed....and sprayed with Krylon satin finish spray coating. I actually did 6 coats. Than I lined the bottom with Dollar tree fun foam using Gorilla glue, spreading it thin and even over the whole 4x4 piece of fun foam, with an old gift/credit type card.
