I think that would make a fab blog Nikki to be perfectly honest!
My blog is rather random; sometimes it shows off a few Etsy Treasuries. Sometimes it will be about a current project, or a new piece of glass. I've blogged about a social media course I've been on, exhibitions I have been to see, other artists, or occasionally random stuff like the time the hot air balloon crash landed on the green in front of my house.... I try to make it relevant to what I do, but also an insight into me.
I agree with Scarlet, I think a good mix is far better than "look at what I just listed" - if I wanted to know that, I would go straight to the shop.
And Nikki, to be honest, I am *not* totally sure how much extra space it would take, etc, but it would certainly involve extra work... for the Frit Happens Fairy for sure
