Throw pillows from men's shirts

I found a few men's button down shirts at the local thrift shop, and decided to turn them into throw pillows.  First, measure the pillow insert.  Cut the front and back panel of the shirt about an 1" larger to allow for seam allowance.  Place right sides together and sew together with 1/2" seam allowance.  Instead of trying to align the patterns front and back, I turned the back fabric panel so the patterns ran opposite.
