Pinwheel Quilt Block Pattern - Pinwheel Block Variation - Can't Stop Spinnin'

Begin Assembling the Quilt Block Units

1. Draw a diagonal line from corner to corner on the reverse side of each 3-1/2 inch square, yellow and black. Use chalk or a light colored pencil on the black squares (not shown).

2. Place a yellow square at one end of a medium green rectangle, right sides together and edges matching exactly.

3. Sew a seam from corner to corner as shown above, following the marked line on the square. Press to set the seam, then cut through both layers to remove excess fabric, leaving an approximate 1/4" seam allowance on the triangular shaped side of the unit.

4. Carefully press the seam allowance towards the green rectangle.

   Some quilters prefer to press the seam allowance before trimming-back. Try both methods to see which works best for you. If your squares are not made from a very light, transparent fabric, it's fine to press towards the squares on these and all other units.

5. Sew a yellow square to the end of each medium blue rectangle. Trim just as you did the previous units.

6. Now sew a black square to the end of each light blue rectangle. Trim and press as before.
