I’ve had blogs since around 2003. That’s not to say I’m a slave to them and post every day. It depends what I have to say and how busy I am with studio work and life in general. My oldest blog http://indigoblah.blogspot.com is a record of work-in-progress, life in general and things I care about. Lots of art and the occasional rant. I find it helpful as a diary process and personally looking back it often helps me make sense of things, events and art processes that would otherwise have been lost over time.
My other blog http://studiobeegallery.blogspot.com is less wordy usually and mostly just images of paintings and drawings I’ve made. But it may change at any time. That’s the beauty of blogs. They can be anything you want them to be.
I recommend blogs. Just as long as you don’t get too bogged down with them and feel you have to post all the time. Relax into one… you might like it. Great way of getting your work seen, meeting like-minded folk online and you’ll even sell your work through it. Good luck!
