Introducing our chunky hot water bottle cover knitting pattern. This pattern includes several photos showing the steps, final measurements, specific yarn recommendations and information on the rubber bottles needed. The cover is knit in the round. This knits up in less than 2 hours and makes a wonderful handmade gift for loved ones, or for yourself. They are very popular as Christmas gifts. These covers fit the standard 2 litre rubber bottles that can be purchased at most pharmacies.
