Like so many other people, you have a stack of old t-shirts you never wear. Perhaps you've gotten beyond wearing obscene slogans or Strawberry Shortcake logos. Or you feel it's time to retire that “Team Hillary” shirt. Or your favourite old shirt no longer fits over the impressive pecs/food hump you've acquired since high school. Or you've had it with MeFi and you want a way to repurpose/savage your MeFi blue t-shirt. No need to be at a loss! You might just settle for making a different style of t-shirt, but you can also use those t-shirts to make diapers for your baby, clothes for your toddler, or adult-sized undies, skirts or dresses. Or a bikini. Just beware of saggage. I mean, of the bikini, after it gets water-logged. You also might make tote bags or pillows, car seat covers, baby wipes, or dusters. If you get really ambitious, you can make a t-shirt quilt, taking inspiration from the many examples on the net. If I haven't given you enough ideas, you can turn to the ever authoritative and exhaustive AskMe, or you can do some further reading on the topic. Just don't get so carried away that you wind up having to go to work topless tomorrow. Unless, of course, your career path requires that anyway.
