STAINED GLASS TULIPS PROJECT SHEET (CLPKHL009) 17in x 31in. With the right fabric choices, these tulips truly shine! Narrow strips of black are added to each tulip petal before sewing the units together for stunning effect. And the sky-blue batik is such a perfect choice, that you have to look twice to see that it isn’t a stained-glass window! The Creative Grids CGR418 and CGRCUT45 are recommended.
