Block 5 is a block in a block with the center block on point. You will need 4 dark 2 1/8″ squares, 4 light 2 1/8″ x 5 1/4″ rectangles, 2 of the 3 1/4″ med dark squares, and 1 med light 3 7/8″ square.
We will start with row 1 and 3 which are identical. Place a dark 2 1/8″ square, then the light rectangle and a second dark 2 1/8″ square. Sew these rows together and set aside.
Now the middle row and your first square in a square. Begin by cutting your med dark squares on one diagonal.
Placement should be precise. Here is how I make certain I am matching the center of the long side of the triangle to the center of the square med light 3 7/8″ square. Fold the triangle(s), match the ends of the cut long side and being careful to not stretch the fabric, lightly press the fold with your fingernail. Likewise, with the square, fold each side in half and mark where the center is with your fingernail. Now match, the fold in the triangle to the fold on one side, RST, and stitch a scant 1/4″ seam.
Next, place the triangle on the side directly across and do the same. Follow with the last two sides the same way.
You have just completed your first square in a square! Congratulations! If your seams are a scant 1/4″, you will have 1/4″ from the edge of the pink fabric to the point of the center square for adding additional units/borders/blocks without cutting off the points.
Now to complete the middle row, add the 2 1/8″ x 5 1/4″ rectangles, one to each side. If you sew with the square in a square on top when adding the side units and your seams are correct, you will see the side seam will cross a thread above the intersection of the seams attaching the corners to the center. This means you will have perfect points!
Next sew the rows together and you have Block 5 completed.
Remember to match seams. In this case, press row 1 and 3 seams to the light fabric. Also, press to the light fabric for row 2. Once all rows are sewn together, press those seams away from the center row. Your seams will nest nicely and seam bulk is eliminated as much as possible pressing away from the center.
