The Ship at Sea quilt block is constructed from simple shapes that make quick assembly a reality. Wavy blue stripes depict the water underneath the ship and a mottled fabric represents the sky. Both fabrics give the quilt block a somewhat realistic look, but use any fabric you wish, because realism definitely isn't required. I've included instructions for a 12-inch square finished block and a small block finishing at 6-inches square. The small quilt block might be a better choice for a child's quilt.
