I couldn't see myself piecing all of the pie shapes, so I took a shortcut by making two of the units below.
Measuring the circle from the block print-out, I cut the freezer paper circle without seam allowance, centered it on the wrong side of one of the pieced blocks and used the glue stick method to turn the seam allowance back for a perfectly shaped circle.
I then used the largest stitch on my machine to baste the circle on top of the other prepared block and then hand appliqued the circle in place.
After the applique was done, I cut away the fabric below, spritzed the block with water to loosen the glue on the freezer paper and remove the paper. Turn everything over, press and trim the block to size and you're done!
