This is great. I bake quite frequently and there is nothing more annoying than trying to re-soften brown sugar that's been exposed to too much air. However! here is your solution. Just put a few marsh mellows in an air sealed container with your brown sugar and it will help keep it nice and soft.
I've noticed that when a grocery bag that I'm carrying or a school bag gets a little too heavy for my shoulder I grab the bag from underneath to take some of the pressure off. However, sometimes this is really uncomfortable and the bag is difficult to grip. Jonathon Livingston Seagulls bag takes care of this design dilemma by implementing a handle at the base of the bag!
