My Joann's has it. Knitting the Nativity from that book is on my New Years Resolution List. If you can't find it, I will pick one up and send it to you. I love using my 40% of coupons on knitting books at Joann's !
It's apparently not being reprinted so if you can find it grab it. You may have to look on eBay. Here's his page where he mentions it and he says he's going to put them in pdfs gradually. http://www.alandart.co.uk/pages/latest-work
When asking questions ALWAYS post the name and a link for the pattern if you have it.
