After making the Hawaiian Shirts quilt, I make the matching pillow shams. I used the same technique, but on a smaller scale. They have an envelope back and a flange.
The centers of the two pillows are 15" squares left over from the quilt. The small squares are made from left over fabric from Hawaiian shirts (sleeves, yokes, fronts). This is really fun, but I am looking forward to moving on to a totally different project.
