Turtle Cove was designed for the Quilt Passions exclusive turtle batik fabric. It was used for the darker of the blues in the picture. Since these pieces are large, this pattern lends itself to fabrics with beautiful patterns that you want to see. Two sizes are given, 50"x70" and 50" square. Beginner.Kit fabrics are carefully chosen to match the original quilt on the pattern cover, but will vary slightly.
