Lily's Cheyenne Tunic by Hey June
I got this super soft flannel from the thrift store and had just barely enough to make a cheyenne (with a lot of tetris-ing). It was my first time using plaid! I had some trouble with it stretching and my front button placket is not very pretty up close I'm afraid. I forgot/didn't have enough fabric to do the cuffs on the bias but would have liked to. The sewalong was super helpful though.
This is size S, graded out to M at the hips, with the sleeves shortened by 2" as recommended, and narrowed a bit too.
