This butterfly applique is modified from I believe a 1950's pattern. I will try to locate the original pattern that was modified and comment on it here ASAP. I did machine applique with variegated machine quilting thread to applique the 2 pieces down to the background fabric after I used spray adhesive to hold the pieces in place. I was amazed how quickly the process went. This quilt was a birthday gift for my daughter when she turned 25. Now I wish I could find an angel pattern that I could simplify just as much to make a similar quilt for my oldest daughter.
