Step-by-Step Sew Easy Instructions

  1. On wrong side of lighter square, mark diagonal line from corner to corner. This will be your cutting line. Mark sewing lines ¼” away from each side of cutting line. Repeat for opposite diagonal.
  2. Place marked square on top of darker square, right sides facing; sew along marked sewing lines.
  3. Cut sewn squares vertically and horizontally to make four equal sections.
  4. Cut along marked cutting lines to make eight triangle-squares.
  5. Press seam allowances toward darker fabric.

TIP: This method works for any size triangle-square unit. Cut squares twice the finished size of triangle-squares plus 1-¾”.
