Several years ago, I bought a backpack from the Surplus Store on the corner of National and Venice in Culver City. (I love that store. I still go back every time I visit family in L.A.) I carried that backpack to work daily for five years, which is a very respectable lifespan. It had enough room for a packed lunch, a crafty project, and a book (three things I never leave home without) AND a bunch of groceries besides. Alternatively, it could comfortably accommodate clothing, toiletries, and entertainment for a 3-day business trip or, stretched to its limits, a week-long backpacking trip. It had plenty of separate pockets of different sizes so that I never had to go fishing for my keys, wallet, or work ID in amongst the jumble of other random crap. It was a good backpack.
At long last, however, the fabric started to tear around the top of the right shoulder strap--the one I use to pick it up all the time. I no longer trusted it to carry heavy loads without ripping farther. I removed it from service but couldn't quite bring myself to throw it away. After all, we'd been through so much together, and none of the other backpacks I could find offered the same carrying capacity, or so many convenient pockets. I bought two other backpacks whose zippers ceased to function in less than a year, and they barely had enough room for my sewing, lunch, and book, let alone a week's worth of clothing. As Steve and I were packing for a week-long stay on a hippy commune, my eyes kept straying to my poor injured backpack, and I decided it was time to give it a new lease on life. I got out my trusty sewing kit and set to work.
