Maybe the cutest hoodie of all time? This is a simple garter stitch hoodie with a twist – spines! I designed this for my baby daughter but I think the appeal is universal so I graded it for adult sizes too.

We start with a provisional cast on at the neckline and work top down with a raglan construction. After knitting the body, stitches are picked up for the sleeves. Stitches are picked up the provisional cast on and worked up from the neckline for the hood. After that comes the fun part! Using yarn held double to give some structure, we pick up “purl bumps” and work spines from the middle of the hood right down to the hem. Instructions are given for 17 sizes from newborn to 150 cm/60” chest. We include instructions for optional waist and sleeve shaping, and for two sizes of buttonhole if you don’t like toggles.
