    • JOANN HACKS:

    • Sew all seams 1/4" from edge of fabric or drawn line.
    • Remember to check that pieces are lined up and pined carefully so units will fit together.

    1. Organizing Fabric Pieces:

      • Label the three sandwich plastic bags as follows:
        • Square in a Square Bag, Quarter Square Triangle Bag
        • Carefully gather the following fabric pieces that were cut from Fabric Cutting Chart and place in the bag indicated._x000B_

        • Fabric A:
          • Four 4 1/2" squares (Square in a Square Bag)
          • Two 5 1/2" squares (Quarter Square Triangle Bag)
        • Fabric B:
          • Four 2 1/2" squares (Square in a Square Bag)
        • Fabric C:
          • One 4 1/2" square (Square in a Square Bag)
        • Fabric D:
          • Two 5 1/2" squares (Quarter Square Triangle Bag)
        • Fabric E:
          • Four 2 1/2" squares (Square in a Square Bag)

    2. Sew Square in a Square Units:

      • Use pieces from the Square in a Square bag.
      • Refer to Diagram 1, following the steps below.
      • Draw a diagonal line on the wrong side of the four 2 1/2" Fabric E squares.
      • Pin two of the marked Fabric E squares on opposite corners of the 4 1/2" Fabric C square, wrong sides together, making sure corners match exactly.
      • Carefully sew over the drawn lines.
      • To check corner edges, fold outside corner of Fabric E towards seam and fold opposite corner over to cover Fabric C._x000B_If Fabric E and C corners do not line up, or if they are more than slightly off, re-sew.
      • Check the opposite Fabric E square in the same manner.
      • When corners line up, fold back over so seam is exposed and trim leaving a 1/4" seam allowance.
      • Press seam allowances toward Fabric E.
      • Sew a Fabric E square to the two unsewn corners in the same manner.
      • Press seam allowance toward Fabric E to yield one Fabric E/C 4 1/2" Square in a Square unit.
      • Draw a diagonal line on the wrong side of the four 2 1/2" Fabric B squares.
      • Pin one marked Fabric B to a corner of each 4 1/2" Fabric A squares, wrong sides together, making sure corners match exactly.
      • Carefully sew over the drawn lines.
      • Check corner edges and trim if edges match exactly._x000B_Press seam allowance toward Fabric B.
      • This will yield four A/B units as shown in Diagram 1.
      • Put the units aside.

    3. Sew Quarter Square Triangle Units:

      • Use pieces from the Quarter Square Triangle Bag.
      • Refer to Diagram 2, following the steps below.
      • Draw a diagonal line on the wrong side of two 5 1/2" Fabric A squares.
      • Pair the two 5 1/2" Fabric A and D squares._x000B_Pin pieces right sides together so the corners match exactly.
      • Sew 1/4" away from both sides of the drawn line.
      • Cut along the drawn line on both pairs to yield a total of four Fabric A/D half square triangle units.
      • Press seam allowances toward Fabric D.
      • Do not snip off extending corner points.
      • Draw a diagonal line down the wrong side of two Fabric A/D half square triangle units as shown in Diagram 3.
      • Pair the marked and unmarked units right sides together with Fabric A against Fabric D.
      • Pin in place with seams lined up.
      • Sew 1/4" away from both sides of the drawn line.
      • Cut along the drawn line on both pairs to yield a total of four Fabric A/D quarter square triangle units.
      • Press seam allowances as shown in Diagram 3.
      • Trim the four half square triangle units to measure 4 1/2".

    4. Complete the Diamond Star Block:

      • Arrange the Square in a Square and Quarter Square Triangle units as shown in Diagram 4 on the pattern._x000B_Pin units in place.
      • Sew into rows and press as arrows indicate.
      • Arrange rows as shown in Diagram 5 on the pattern._x000B_Pin rows in place, sew rows together and press as arrows indicate to complete the Diamond Star block.
      • Block should measure approximately 12 1/2", but this can vary slightly.
