Valerie Van Sharder's book "Sweet Booties". This pattern didn't really work out for me. For one thing I chose the Newborn size because everything else seem to fit my 18 mos old in that size :o . Apparently little one actually has the head of an 18 month old even though the rest of her body is newborn size. No idea if the sizing is off in the book or its my little one.
Since I have already returned the book, I'll try to self modify the pattern. Hats are a very cute and functional accessory, so it will be good if I have a go to pattern for these.
