How to make yoga capris from an old t-shirt or two. You can change the sizes of the pants by the sizes of the t-shirt. I used an extra large adult t-shirt for mine and i can wear jean sizes 3-6.For my little sister i made a pair using an extra large in children's for her pair. Special thanks to Livia for helping me with this video (she is the one modeling and making the pants!).I got this idea from TK Rainy's "Yoga Pants Keep That Logo On Your Tshirt!" This was the first time i made the pants, so enjoy and let me know how it works!
