Aunty Biscuit acquired a very long, thin hot water bottle which has a novelty cover.  At some point this is going to need a spare cover. This then leads to the dilemma of whether to go for a relatively plain cover maybe stripes or a simple pattern, or something a little more exotic.  Perhaps a snake or a daschund?  Maybe something in leopard spots or zebra stripes? I will wait and see whether the sketchbook or yarn and needles appears first.
