The Exploding Nine Patch Quilt Pattern from Everyday Stitches is a diverting trick eye illusion. The 20" nine-patch blocks burst off the quilt when three variations of the same color are pieced together. The Exploding Nine Patch Quilt Pattern includes detailed instructions to create a 60" by 80" throw and an 84" by 84" full-size quilt with a suggested list of materials for each. This pattern is scrap-friendly and easily scalable to any size needed!
