This is how I made the Pinterest pages for my school. This is as close to a step-by-step process as I can give. The best way to learn it is to play around with it yourself. Once you get the hang of it, it’s easy.
I started a Gmail account for my library and chose a password that I would feel okay sharing with other people. I want my aides and any other librarian who might follow me in the position to take over the social media accounts. I use this account for every social media account I use for my library.
