I started blogging again in July using this blogging template and it just works for me. It has a space for ideas so I can jot them down as I think of them and then a place for me to actually schedule my posts. I originally read Em's post on staying organized with blogging and it inspired me to create one for myself (with fonts I use in my brand).
I keep this clipboard on my desk or in my bag when I travel so that I can quickly jot down ideas. By the end of the month the margins will be full of ideas which I then transfer to a google doc for safekeeping. I keep it on a clipboard taped down with washi tape so the edges don't get torn!
I hope this helps you to stay organized with your blogging!!
