I have made a lot of toilet roll covers. Some were for our Toilet Roll Covers book; some have been of a more mathematical nature. What could be simpler than this one that uses counting numbers, which fit very nicely around a toilet roll.

You will need less than 50 metres/yards DK in each colour.

The ebook contains patterns for eleven knit and crochet toilet roll covers based on mathematical concepts. It also has a section that will help you to design your own covers.

The patterns are not available individually but if you want just one I can supply it in return for a small donation to my favourite charity.
