I think it is best to write what you are passionate about and hopefully you will find a following of like-minded and inspired folks. I write on a variety of topics, usually what I am pondering or working on at the time. I don't have a smart phone and am bad about taking pictures during the process of whatever I am making. Steemit folks like their photos, so I will have to not only take the pictures but put them on my laptop. :-)
Right now I am in the middle of finishing off a blanket shawl for my daughter. When I get in the knitting zone, it is sometimes hard to do anything else.
Take care @fernowl13!
