This afghan is based on a design sent to us by the famous Oxford mathematician Sir Roger Penrose. It is named in his honour.

The first Penrose afghan was the red, yellow and orange version. It was bought by the London Science Museum for their Mathematics Collection. The second was in shades of green to give a very different effect.

The instructions are very easy to follow and you can use any yarn you choose, though your choice will affect the overall size of the afghan. It may look complicated but, if you can knit garter stitch, you can make this. You work with one yarn at a time to create eight sections which are then stitched together.

You do not have to work to a particular gauge. A colouring sheet is included so that you can try out your own colourways before you begin.

The booklet also contains information about the aperiodic tiling that inspired the design.

Read the story of this afghan on Ravelry or on Woolly Thoughts web site.

The pale version of Penrose was made by my mother, who died on July 31, 2008. We are making a donation of £1, to Kidney Research UK, for every copy of the pattern sold. Click here to see why we support this charity.

If you would like to start with something smaller, we have a cushion version of Penrose.

The cushion pattern is also available in our Cushy Numbers book.
