  1. Yay! too bad I don’t have any wool of the right weight. If only I’d known when I put in my yarn order yesterday. Oh well, reason to shop, right?

    Thanks muchly! My money will be going to the American Brain Tumor Association. 🙂


  2. I was just looking at a knit water bottle cover in the store, thinking someone must have a great pattern for one of these… Thanks!


  3. Thanks for the pattern . I was just thinking that i needed something for my water bottle , i was getting really sick of using a towel it just never seemed to stay in place . this looks like it will work great.


  4. Thanks for this free Pattern.
    Entering for a competition in the Women’s Institute and covers go to the local Rest Home for the elderly.


  5. Thanks for the Hot Water Bottle Cover. It will save me going into the loft and hunting for my old patterns. I will have to sort them out. I know I have one somewhere up there. Thanks again.


  6. if you start with 28 stiches and cast off 2 lots of 9 how do you end up with 20 atitches – I cast of 6 and carried on with 16 stitches and it is ok but I would like to get it right


    • Hello Rosemary,

      Thank you for the comment. I’m sure you’re correct that you should end up with 16 sts. I wrote the pattern a long time ago when I was new to designing and I’m afraid I didn’t have anyone check it over. In addition, I don’t even have the original hot water bottle cover any more! I made it for a swap and sent it off to pastures new just after I’d made it!

      Thank you for bringing this error to my attention and I hope I didn’t cause you too many hair-pulling moments.

      If there’s anything else I can help you with, just email me.



      • Thanks! I guess I’m just not using bulky wool so it looks a bit small, but it will stretch. I’m a fairly new knitter and just finishing up the first side of this.


      • You may struggle if you aren’t using a thick enough yarn. It’s a snug fit as it is (especially over the neck of the bottle) so you may need a smaller water bottle! 😀


  7. Amy, I want to use your pattern, but the glorious wool I’ve found is double knitting wool. If I use 4.5mm needles with this wool, how many extra stitches should I have? Would you say double the amount? And then adapt the neck to fit?
