That's why I got really excited when I saw Missy's tutorial on Cut-Out-and-Keep for making a no-sew circle scarf out of a t-shirt. :)
The only thing I did differently was keep my ends separated and used the sleeves of the shirt to make fringe.
Her tutorial goes into a lot more detail but the gist of it is cutting 1" bands starting with the bottom of the shirt (after cutting off the hem), stretching the bands, looping each band around your hand a few times, then tying the bunched up loops together. It took me about an hour from start to finish which included the time I spent using the cut off hem as a toy for one of my kitties.
