One day I was rushing to the train and my laptop strap broke. I cursed my luck and found something in my purse, tied it on, and made the train just in time.
As it turned out, my rigged handle was incredibly comfortable; it stayed put and didn't dig, while also making the heavy laptop feel light. When I got to the train, two women stopped me to compliment me on my “very pretty bag” and asked where I bought it. I laughed as I explained that I had rigged it just a few moments before out of desperation… and the idea was born.
