I just came across the El-cheapo Shirt Challenge and I love it.
It reminded me of this old shirt I made for TheBoy a few years ago. I took a stained t-shirt, dyed it, painted it and added outgrown legs from pajama pants to make it warmer.
It looked far cuter in person (wow, this is a really awful picture, isn't it? I'm sorry about that), but this gives you the idea. I paid a quarter for the t-shirt and everything else I had on hand.
FYI, there are lots of super cute shirts linked up, but this postcard one is my absolute favorite. How cute!
