Can It!

I have been collecting canning supplies for about 2 years now, maybe longer but who's counting?  I really, really want to learn, but haven't taken the plunge yet.  So, yesterday I bought a beginner canning book, yes another one.  It also covers freezing and drying.  I think I will start with blueberries, blackberries, and strawberries.  Those will be coming in soon here.  Any thoughts? I'm scared to do this, I really don't want to poison my family or anything of the sort.  I do like my kids and would like to keep them around!  Someone has to take care of me when I'm older!
