Sweet idea for a beach or nautical theme. Combined with sand, driftwod, candles and a few flowers and succulants (like those seen at the beach) it would be really beautiful and inexpensive. DIY: Oyster Shells as Toy Boats
Check out these great driftwood sailboats with sails made out of nautical-look fabric scraps. I think you could also use long breadbaskets as the boat bottoms and put the bread for your buffet in them!
