Intro These handy baskets are one of our most versatile eco-friendly products. Handmade in Brazil, these baskets are a stylish storage solution. Our baskets are crocheted with t-shirt cotton yarn and work well for toiletries, kitchen utensils, makeup, jewelry, and so on! What's Recycle T-Shirt Cotton Yarn? T-shirt yarn is the easiest and most forgiving crochet medium. T-shirt yarn is also known as "tarn" and T-Yarn. It is made of leftovers from t-shirts. This is because the cotton has been well worn and perfectly soft and still durable, and just slightly stretchy.
