My Mum says that with a hot water bottle you can beat the cold when you are staying away from home. You only need hot water to fill it and it takes virtually no room in your suitcase. What could be nicer than to have your own luxurious cover for your favourite travelling companion? It is perfect for keeping you warm or easing out the cramps or aches from the day. Simple stitching is needed which allows the beauty of the Noro to shine.
