That quilt is made of only one block, turned different ways, so you only have to draft out one block, and make it in different colors. Sketch it out the size you want on graph paper. When you sketch it you have to sketch it with lines drawn where each seam is on the pieces. (In other words, you don't draw out the square which looks like a picture frame as one piece of fabric.) After it is sketched, just measure each square and rectangle in your sketched pattern, and add a half inch to the length and a half inch to the width of each piece to get the size you need to cut the fabric for that piece.
