How to make a drape t-shirt. A tutorial. (Unfortunately not for this image/shirt, which I love.) Draping tutorial is still good for measurements, but will have to try to figure out this black gray stripe design some other way.
If you have long arms (like me) and a bunch of long-sleeved tees that don't fit after one wash and dry, you're gonna love this idea. DIY – Long sleeves to short. adding long sleeves to a short-sleeved shirt HAHAHA
