Sewing Instructions:

Step 1: Using a rotary cutter and ruler, cut eight Color C 3-7/8" squares once diagonally for a total of sixteen triangles.

Step 2: Stitch a Color C half triangle (that you cut in Step 1) to two opposite sides of a Color A 4-3/4" square as shown below. Press seam allowances toward Color A fabric and trim points. Stitch a Color C half triangle (that you cut in Step 1) to the two remaining sides of the Color A 4-3/4" square as shown below. Press seam allowances toward Color A fabric and trim points. Repeat for a total of four A/C units.

Step 3: Stitch a Color D 7-1/4" quarter triangle to two opposite sides of an A/C unit as shown below. Press seam allowances away from the Color D fabric and trim points. Stitch a Color D 7-1/4" quarter triangle to the left side and stitch a Color B 7-1/4" quarter triangle to the right side of the A/C unit. Press seam allowances toward the center of the block and trim points. Repeat for a total of four A/B/C/D units.

Step 4: Using a rotary cutter and ruler, cut four Color A and four Color B 6-7/8" squares once diagonally for a total of eight triangles of each color.

Step 5: Stitch a Color B 6-7/8" half triangle to the upper left side and a Color A 6-7/8" half triangle to the lower right side of an A/B/C/D unit as shown below. Press seam allowances toward the center of the block and trim points. Stitch a Color A 6-7/8" half triangle to the upper right side and stitch a Color B 6-7/8" half triangle to the lower left side of the A/B/C/D unit. Press seam allowances toward the center of the block and trim points. Repeat for a total of four Square in Squares blocks. Each block should measure 12-1/2" at this point. They will measure 12" when we sew them into the quilt.
