I started using OneStopforWriter’s website. They have various tools with which to build your characters, settings, and plot. I’ve picked out three positive and three negative traits for my main characters. Some things have occurred to me as I did so that helped flesh them out. I will continue to work on the characters till I get them where I want them, then move on to the setting. After I get the world building as intricate as I want it, I will bring the minor characters into the fold.
I like to know my world a bit better before fleshing out the remaining characters so I can see how they’d react to it. Some authors might do things differently, beginning with the setting and then peopling it but I like to start with my main characters first. OneStop has various templates you can download if you subscribe to them that work with either word or as a pdf. You can keep notes on OneStop as well to keep your project altogether.
This is the first time I’ve used the templates and notes and I’ve found them very helpful. Plus, Becca and Angela have a wealth of info in their stacks and thesauruses. It’s designed to help the writer advance their project and it does that for sure. I hope you give their site a try.
Have a great week, take care, and God bless!
