Ssetting up my blog or HELPPPPPP

Now seriously how hard can setting up a blog page be??? Well actually if you are my age, and a non techie it is definitely a challenge but  More error I'm sure.  I got this far now to  design my space.  First, what is  my blog be about?  Just what it states, " A little bit  of this and a little bit of  that.  One thing for sure it  will be an adventure, and pictures.  So I am feeling my way.  In the future I will talk about books I have reviewed, sewing projects, knitting, places I have been and if you have any suggestions then please ler me know.  I hope to make it fun and interesting. I will be asking for your help....Good night
