2. Pencil in the design shape you want to create on graph paper (figure D). For each unique square, sketch a key of it to the side of the graph.3. Assign fabric squares to grid squares. Look for markings on fabric that mimic the shaded squares. For instance, if you have a square with diagonal shading, find fabric with a diagonal marking on it to assign to that square.
4. Place assigned fabric squares onto a background of lightweight, grid-lined fusible interfacing, mimicking the pattern drawn on graph paper.
5. Use a hot iron to fuse fabric to the interfacing. Move and adjust your ironing board so you can easily slide the quilt top from your work surface to the board, pressing a small section at a time until it is completely fused down.
