Design based on NFL Jersey.

Basic bodice and sleeve instruction loosely based on Knowles "drafting the sloper set" (p35). I simplified the instruction for less measurement and shaping.
All steps recorded. You just need to add graphic and topstitches.
Fabric: Knit. I use cotton rayon.
Below is the overview of the basic block, not the final pattern.

For a short sleeve like this one, I make sleeve cap height taller because it just looks nicer that way. I real world, the sleeve cap height is usually shorter for comfort and mobility.
