What is even better about this project is...wait for it....no sewing required! Woohoo!! Makes it super easy to do.
1 old tee (the larger the better)
1 pair of sharp scissors
1 ruler
Start with a large tee. Any old shirt will do that does not have graphics past the armpits! Make sure it's seamless. If not, don't sweat it- that can be the point where you wrap all strands together!
Cut off the bottom hem of the tee. Then cut 1 inch wide strips horizontally across the shirt from bottom to armpit. You can cut as many strips as you would like and if you want you can also make them varying widths. The more strips, the more strands your scarf will have. If you want to be exact, you can measure each strip. I didn't measure, simply because I'm lazy and wanted to get it finished.
Stretch all of the remaining loops until they become long and noodle looking, and the raw edges start to roll inwards.
