Pinterest is a familiar application for a lot of us. In my first look at Pinterest I thought of it as a way to collect the things you like that you find the net. I did not use it a lot at first. Then I saw how people are using it to market their products. There are seminars on how to use Pinterest this way. Then there are the Artists who are using it, Some use it to show off their work and others create boards of inspiration. This can really be fun to do.
Now how can writers use Pinterest? There are several ways I use Pinterest for my writing. First the simplest way is to create a board about your Work in Progress. There are a lot of writers doing this. Its nice to have a visual of what your characters might look like, or the setting or of the events that will happen in your story. I like to look at my board to keep me into the story, to keep me motivated. Motivation for writers is always a good thing. But how else can you use it? I have boards for possible future characters, favorite scenery, costuming ideas, Words of wisdom, and more. The ideas are only limited by your imagination.
I print out pictures and put them in my notebook when working on my outline. Sometimes I create screen savers of all the pictures for my novel. I did that for NaNoWriMo last year and it worked great. Pinterest is a fun tool for writers but its easy to get sucked into spending hours on it. So you may have to work on limiting your time on the site.
