I have a book by Jan Eaton on crocheting and have taught myself using this book. I am convinced from all the photos in there that you are meant to put your crochet hook through the stitches - either from the front or the back. However now I have read the introduction of the Happy Hooker and she says that after the first row, you put the hook underneath the stitch, so in effect under two strands of yarn.
Is this an either or thing and both are ok or have I misunderstood and been doing it all wrong?
