Why write a blog?

I've been thinking of writing a blog for a while now. This is surprising as I've never thought of myself as a particularly good writer, nor an outgoing person. I'm hoping the blog will be a place where I can put my thoughts into writing as well as share some of my quilting and knitting adventures. I also hope that since I have a blog, I'll be more accountable. If I say I'm going to make a quilt, I now have to make it as I need to publish the results!
I've called it "Lindivine Designs" as I would like to create children's clothing and accessories. This is a bit of a way down the track at the moment though.
So, welcome to my blog!
