I am working on my own project. I am the only developer, but we hope to grow some day, so I want to have everything organized for the future developer.
What do you think are the best practices to branching a repo on Git?
In my mind, version control tools like git and Mercurial are super flexible by their nature. As a result, looking for the "one true model" is a fruitless endeavour. It's almost a personal preference, based on how you like to work, and what you want to do with your project.
I've tried git-flow, and while I liked it many others haven't. It's similar to how I naturally work, but I can see why others feel that it is overkill.
If your stuff is in version control in the first place then it is unlikely that your source control methodology is going to vastly affect the project, and how things might move forward. History is good, but the joys of source control is that it doesn't dictate how you move on in the future.
My recommendation is to read up on every source control workflow you see here, give them a try on some personal projects, and then pick what you like the most and go with it. They all have their good points, and by playing with them you'll see what works well and what isn't needed for you.
