A red strip is used on the Herdwick sheep to identify them to the farm. Every farm has a certain sign on the sheep so if lost they can be traced and sent back to their farmer. Burnthwaite farm is a red long strip across the side of the sheep.
I will use this red strip in the sewing onto of the photo, maybe on one of the sheep images? or use red tread to symbolise with red strip onto the land.
