This is the same basic design as the first Christmas Quilt - just using Halloween or scary prints - aliens, spiders, skeletons, cobwebs, pumpkins and the like. I use black for the backing and appliqued on 5 white ghosts. I also added 5 long claw scratches bottom right hand corner - see the red flesh underneath?
"Ridge and furrow" is result of ploughing with non-reversible ploughs on the same strip of land each year. It is visible on land that was ploughed in the Middle Ages, but which has been managed continuously as grassland since then.
