Spot the Deliberate Mistake

I ordered myself a new quilting book, and my parcel of delight arrived today from Amazon. However, when I eventually burrowed my way into the box, this is what I found. And yes, I was charged twice. Looking on the bright side, I have my friend's birthday present sorted!

Now I shall make myself a lovely cuppa and snuggle up in bed with my new book. I haven't even peeked inside yet. The will power is strong tonight...
