I am really happy that I just found this site. It teaches how to do chain free crochet. This technique gives the edge of your work the ability to stretch, unlike when you start with a chain. I think this will make it much easier to create hats that are worked from the brim up because you won't have that tight chain at the bottom.
There are pages that teach no chain single crochet, half double crochet and double crochet.
Hope someone else finds this useful!
Thanks for looking and happy crocheting!
