This is a pattern for "sleeves" aka a shrug / bolero / you get the idea. The design features a raglan granny stitch yoke seamed to two tubes of granny squares and finished with a double crochet trim. This pattern includes instructions for making it to your size and includes a video tutorial:

I used mohair yarn, but I invite you to use what you like! The mohair creates the most ethereal, floaty sleeves. Holding them up to the window, the granny squares reminded me of stained glass and crocheting this was the most delightful experience.
