From Huckbyshappilyeverafter.blogspot and pinned to my "DIY, things I've made, or will make": coasters from 3x3 bathroom tiles (16 for $10.99 - 15% at Menards. Staz On Jet Black Ink, acrylic stamp (12" long, cut in 2) from POSSIBLY www.paperwishes.com, circa, 2009, but I could be wrong. P.S. Keep rubbing alcohol close by to wipe away mistakes, rinse, start over. Also - I didn't use the turtle wax as in the org. post. Didn't like the finish, but like the "thirsty stone" effect.
