Clarence, the hot water bottle cover. Not just a hot water bottle cover, but a beautiful, cabled, patterned cover, made with pure merino chunky wool. Soft and warm, ready for cosying up on colder days or nights. 
If you use superwash wool, Clarence will enjoy a gentle bathe in the washing machine at 30°C. 
Make him for yourself, sell him at your craft stall or give as a gift this Christmas ready for those winter months.
