Click the link above to download your free PDF pattern. You can print it out on pieces of paper like tiles and stick it together to make a full size pattern. The first one is set up for A4 paper and the second one is set up for American Letter size.
This pattern takes 1 metre of fabric (standard 150cm/ 60inch width).
All my free sewing patterns are made to fit a UK size 12, but can be easily adjusted at key points to go larger or smaller. Have a look at the Making a pattern fit page for how to do it.
