My favourite shape is the hexagon, so the second design in the book Cowling Around uses the hexagon.
Made in 5 colours, but could be varied as much as you like.

Approx 21cm deep by 175cm around.

All patterns in the book are written in UK crochet terms and are charted.

The book is available as hardcopy (with ebook download) in my Etsy shop or as an ebook here on Ravelry.
