A beginner’s delight knit on #10 needles in Garter Stitch. The simple shape lends itself to an array of yarns and textures, each fiber creating a different mood and a different use for Sasha. Toasty and warm knit in homespun yarns or raw wools for layering, or a little more elegant, and with some drape, in rayon, silk or alpaca blends. Try it in different yarns for different purposes.

Sasha is easy to finish as the back and front shoulder and sleeve stitches are joined with the Knitted Seam Method; only the side and sleeve edges are sewn together.
