Need a quick baby gift that you can finish in an afternoon? Sparkler is it. By cutting the B template from the same fabrics, the yellow pinwheels create a secondary pattern when the blocks are sewn together. The blues and greens are cut from eighteen 10-squares so if you like the colors, you could make two baby quilts from one 40 pack of squares. Since there are no sashings or borders, the quilt goes together very quickly. An added bonus? Since it measures 36-inches square, 1-1/4 yards of 42-inch-wide fabric works as a backing, no piecing required. Or use a 60-inch-wide plush backing to really make that baby smile! 36in x 36in. The Creative Grids CGRMT6 is required. Project Time: 2-6 Hours. Fabric Type: Square Friendly. Project Type: Quilt.
