PEBBLE TRIVET AND COASTERS

You need small smooth flat pebbles, quart jar lid for each coaster (like a mayo jar lid), large metal lid for each trivet (such as with wide mouth lids for gallon jars), plaster of paris, acrylic finish or acrylic floor wax
Mix plaster by directions. When it starts to get thick, spoon into jar lids til half full. Select pretty pebbles and press into plaster - you may do so at random, or create a design. The plaster may squeeze up and out of the lid, but it can be wiped away later. Let plaster harden, then use old socks and rags to wipe away any messes. Throw the rags away - they won't come clean in the wash. Brush a coat of acrylic finish or acrylic floor wax on. You may want to glue felt scraps on the bottom to prevent scratches on furniture.
