100 Ways to Transform a T-shirt: (1) This 100% recycled, earth-friendly yarn is made entirely from t-shirts. One 3XL shirt can make roughly 70 yards! Tie dye the T before cutting to really mix it up.
Pictured is my own yarn, but you can find an easy to follow tutorial through THIS link. :)
Truebluemeandyou: Really good tutorial from Craft Passion. I’ve seen some amazing crafts knitted out of tee shirt yarn.
