Blue Windmills

This is an American quilt dating from around 1940 which now belongs to Ann Jermey. The blue windmill sails are all slightly different fabrics. Can you spot the deliberate (or otherwise?) mistake? You can’t help speculating about the reaction when the original maker of the quilt spotted it – presumably after the quilting was done, or perhaps once the top was all stitched together and it was just a bit too much unpicking to be worth the effort!

The finished quilt measures 60 x 85 inches and can be made with scraps or a more controlled colour palette - your choice!
