3 inch 3 ring binder

I am just a normal guy, looking to make a 3 inch 3 ring binder cover. I've watched a few videos of basics, which gives me a starting point. Now, I'm looking for a template to follow so I can get one put together. Does anyone have a good source to look for this template, I haven't had luck. Depending on what is needed will determine which tools I'll need to buy, right?
