There was nothing else for it, I'd just have to open one of them and find out.
This one was particularly weighty and had a definite Bookish feel to it... and I was right!
Paula had been checking out my Amazon wishlist and spotted this book of Jane Austen inspired crochet patterns in amongst the craft books. What an amazing, thoughtful gift! Thank you Paula! You can see the patterns in the book on the book's Ravelry page here.
I can't wait to get my hooks out and get working on these!
