This is my variation of the hot water bottle cover made from a sweater. I wanted the hottie to be completely covered in woolly goodness but easily filled and emptied - without having to take off the cover every time. So, inspired by those fingerless gloves that convert to mittens, I came up with the idea of the flip top. If you'd like to keep your toes warm, read how I made it here.
The top photo was taken in July last year driving from Christchurch to Dunedin via Lake Tekapo.
