I have previously shown the pattern for this mini hot water bottle cover with a lavender bag in the pocket. This pattern fits a mini hot water bottle from poundland (my local poundland still has plenty in stock). I decided to make these extra two with some left over yarn (there was just less than 50g of DK yarn left on each ball, and this was enough). The fabric was also leftover from some bags I made.
I didn't do these ones stripy so they were really quick to knit up.
