Took some ideas from other pins to create this Tic Tac Toe. I used Rhubarb leaves in base of mold with a bamboo frame for separating the board squares then covered in cling film and poured cement (two parts cement powder, one part building sand, mixed with a little water), shook gently now and again to release air bubbles and then painted it when dry. The little leaf is a holder for the painted bug pebble counters.
