I needed a bag for school that could carry my laptop and a notebook or two. Knowing that the pattern wasn't large enough for my laptop I increased the size about 20% making it larger. This worked out great and I like the bag a little bigger. I used laminated cotton and canvas, I love having a waterproof bag. The pattern was pretty straightforward, no hand holding though. Which is fine, I am used to patterns, not for a beginner for sure! Love the result!
