There are no instructions for a second shoe sock/booty. Be aware that you need to knit a mirror image for the second sock - keep the buttonhole to the RIGHT of the needle when knitting the left booty. Also when you are knitting the sock top and have picked up all the stitches as suggested you will have 42 stitches NOT 49 stitches. There are numerous errors and typos in this book, but I haven’t found a site where errata are published.

Chrissie Day is a prolific designer - I’m sure the errors in the book are down to bad editing. Charts would have improved things.
