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.

Rolling Around is a collection of simple patterns, each inspired by a mathematical idea.

This simple modular cover is based on our popular Windmills design. It is quick and easy to make using about 40 metres white DK and about 30 metres of the contrast 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.
