This modular jacket is knit with a worsted weight gauge using fingering weight yarn held double. The construction begins with sleeves in the round. Stitches are picked up and worked towards the center of the garment. The shaping is simple and square for easy garter stitch knitting. A short row collar and I-cord border add a pop of color. The final shape is generously oversized with two openings for each arm so you can flip the jacket upside down for a longer dramatic look.
Sample is shown in Large on a 41"/104cm chest circumference. Jacket is mean to fit with a large amount of positive ease in both sizes. The Medium size's width is a bit shorter and the length is considerably shorter. It could be made longer by picking up sts and adding an extra border at the end.
