The Alcea Cowl by Hannah Maier for Knit Picks is just such a project. It’s worked almost entirely in Stockinette Stitch, and stitches are strategically dropped and allowed to unravel to give the piece an airy feel without a lot of work.
It’s knit flat, too, so you can make it whatever size you like, or however long works for the yarn you have.
