Crocheting Afghan Using Bulky Yarm

I have been crocheting for many years but I would consider myself just a beginner as I have trouble trying to understand patterns unless they are shown to me.  Youtube has helped a lot but I find this site very helpful as well as you show how to do stitches with photos.  I would like to learn more stitches so that I could make more afghans and/or other work.I am in the middle of making a crochet afghan using bulky yarn.  I haven't seen anything on the internet about  this so I think it is quite unusual.  It is difficult to work with once the afghan begins to grow but I enjoy doing it.  I have used to different stitches throughout the afghan but I don't really know what they are called.  I'm wondering if anyone else has ever attempted to crochet an afghan with bulky yarn and if so, what stitches were used.  I find this site to be a wonderful source of information!
