Ready to Dive in... I think!

I have been planning exactly how I want to launch my TpT store so much that I haven't done anything with it at all!  I am building content, but it is that fear of actually posting something that is getting me!  I want to do it right from the beginning.  I want to learn from others and hopefully not learn the hard way too much.  ;)  I have a few things, but I just have to get the confidence to click POST!
