OK you guys - you asked and at last I can deliver - Here are some printable files for my Song of Achilles cover. You can download the full size ones here: https://joshchmartin.wixsite.com/mysite/book-covers - just scroll down to the Song of Achilles cover and click on it!
I figure most of you will be printing out at home so I added some tabs so you can print out each part separately on A4 and stick them together yourselves.
