Bags

So I rode my bike to campus/class/work this morning and had to switch out my bags before doing so. I definitely need a large, sturdy, comfortable bag to carry my books, laptop, food, and incoming mail in.

So, of course, I was browsing Etsy looking for bags that fit the above prescription and came across so many super cool shop! Wanna meet them?

Rainbowswirlz has this super cool skull bag:
Love this Swallows bag by Stevester:
Rejoicebags has some super fantastic choices as well!
What is your favorite bag that you bought or are drooling over on Etsy?
