Mix the cement, peat moss and vermiculite together in the wheelbarrow.
Slowly add water until the hypertufa mixture is damp and holds together.
Line the plastic bowl with the hypertufa mixture, using the trowel, to a uniform 2-inch thickness. Put on the gloves.
Position the ceramic tiles in the hypertufa to create the mosaic, beginning in the center of the bowl. Press the tiles firmly into the damp hypertufa.
Let the hypertufa dry for three days.
Cut the bowl away from the hypertufa with the garden snips.
Cut four lengths of rope to at least 3 feet each. Gather the rope lengths together and tie a knot at one end, letting 3 inches of rope ends fall below the knot.
Place the rope knot at the center of the outside bottom of the bird bath. Gather and tie the rope end tops to a tree branch.
