Jen Kingwell's Postcard Projects are simple and wonderful. Use the template to cut a variety of fabrics to make a scrappy, happy quilt! Each Propeller is 2.5" tall and 1.75" at the wide end.
Propeller Postcard Project #9 can be stopped at any size. Instructions are included for hand piecing but can also be completed using a machine. But really, this is more fun to hand piece :-).
