Slayer ketti's backpack

This is the backpack that I use at school, every day. It's been everywhere, for example I've used it as pillow and when I woke up it was at puddle (so it's good that these patches are nothing rare, they've seen a lot). I wonder how many of the other girls at my school despise it but I must say that I love it! I'm maybe gonna add some new patches to it later. Hipster brand maybe, but hipster backpack? Never. What do you think?

update: changed some patches!
