If you were to use drift wood this would be awesome for a beach reception style thing. Very natural, but striking. Drill holes in wood, place tea lights. Beautiful outdoor table center piece for the picnic table---AROUND THE GARDEN POOL
Elmer's Glue on Canvas, then paint the whole thing. I have totally done this, but with a hot glue gun. Elmer's Glue seems to be a better idea since hot glue leaves behind strings and is harder to work with.
