From Sallie Tomato:
Tripper is a functional backpack that can also be used as a diaper bag! This pattern has been cleverly designed to avoid using any bias binding. The name of this pattern was inspired by the American sitcom, Three’s Company.
I'm confident that anyone can make this bag if they want to! It's not a quick sew; however, it's a very functional bag and well worth the time! There are quite a few pieces to cut, which can make this bag seem intimidating, but if you take it one step at a time, the bag will come together before you know it! When you're done, you'll feel very satisfied and accomplished!
