1. Cut 2 squares at 9.5" square.
2. Cut each of these on ONE diagonal, corner to corner, to create 4 triangles.
3. Fold each triangle in half along the long side of the triangle, pinch the fold on that long side to mark the middle.
4. Apply triangles to opposite sides of the block; trim off the overhanging points even with the block edges. (Note that the triangle will be "too big"....you want that!)
5. Apply the remaining triangles to the other two sides of the block. Trim.
6. Now you will notice that your block can be placed into a quilt without losing the points of the block because you used triangles that were larger than absolutely necessary.
