"Hourglass" Wholecloth Mini Quilt

This is my first wholecloth mini quilt and my 14th mini quilt for my personal "I Walked the Line Walking-Foot Challenge". I used Melissa Marginet's "Edge-to-Edge Walking Foot Quilting Designs" book to learn how to set up the "grids" for this pattern. Fabrics used: "Shadow Play" by Maywood Studio for the background; Kona Solids Black for the binding; and Cotton Painters Canvas/tarp for the backing;
