Cool for School Messenger Bag

I made this messenger bag for my niece for school--it was my first non-tote bag and much easier than expected! This is the second bag, I tweaked the strap to make it heavier duty and adjustable and added my very first magnetic closure (which hopefully doesn't rip out the first week it is used). I hope she likes it! I actually already have orders for at least two more, plus I'd like to make one for myself...
