Between Aaron and I, we have a ton of tee-shirts. With the move, Aaron cleaned out his closet and had a bunch that he wanted to donate. I decided to use them to make into tank tops instead.
Just a simple, drawstring top. If you're industrious, you could probably whip out a couple in an hour.
Since I'm toying with the idea of selling these at the Farmers Market and in my Etsy shop, I'm not really going to give directions just yet, but believe me when I say they're super easy and they look darn cute with jeans.
