# How to Knit a Hood: Shaping, Attaching, and Finishing
A well-made hood can turn a plain pullover into the coziest thing in your closet, but it's also one of those techniques that looks trickier than it is. The shaping happens gradually, the "seam" at the top is usually invisible, and the whole thing is built from skills you already have: picking up stitches, increasing, and joining live stitches together. Once you understand the shape you're actually building — essentially a fabric bag that curves around the back of the head — the rest is just following the curve.
In this guide, you'll learn how to attach a hood to a finished neckline, how to shape it so it fits instead of standing off the head like a paper bag, how to close the top invisibly, and how to finish the face opening so it doesn't flop or curl.
Understanding Hood Construction: Two Approaches
Before you cast on or pick up a single stitch, it helps to know there are two common ways to build a hood, and most patterns use one or the other.
Picked-Up-and-Worked-Flat Method
This is the approach used by the majority of pullover and cardigan patterns with hoods. Once the body and neckline of the sweater are finished, you pick up stitches directly around the neckline opening with the right side facing you, then work the hood upward and backward from there, shaping as you go, and closing the top when you reach the finished depth. Because the hood grows straight out of the neckline, there's no separate seam attaching it to the body — only the ridge or curve at the very top needs joining. This method produces the least bulk around the neck and is the one most knitters mean when they ask how to knit a hood.
Two-Mirrored-Pieces Method
Some patterns instead have you knit two mirror-image pieces separately (or one piece worked flat and folded), each shaped like a rounded flap, then seam them together along the back-of-head curve and finally sew or graft the whole assembly onto the neckline edge. This method is more common in sewing-pattern-style construction and in some structured or lined hoods, since it gives you two flat pieces that are easier to underline or interface. For a standard knitted pullover hood, though, the picked-up method is simpler, seamless at the neck, and the technique this guide focuses on.
Step 1: Pick Up Stitches Around the Neckline
With your sweater's neckline finished and bound off, use a needle a size or two smaller than your body needle (many knitters like a short, skinny circular for this) and work around the neckline with the right side facing you.
- Insert your needle into the fabric just inside the edge, wrap the working yarn, and pull a loop through — repeat evenly around the whole opening.
- On stockinette edges, look for the "V" of a stitch just below the bound-off edge and pick up through it rather than through the very edge, which keeps the join tidy.
- A rough guide is about 3 stitches for every 4 rows along vertical edges, picking up 1 stitch per stitch along any horizontal cast-on or bound-off sections, then adjusting on the next row.
Once you're back where you started, count your total. It's normal to be a few stitches off from a clean, pattern-friendly number — increase or decrease evenly on the next row to land on your target count, rather than trying to force a perfect pickup the first time.
Step 2: Shape the Hood for a Real Fit
This is the step that separates a hood that hugs the head from one that gapes open or chokes at the neck.
Add Width Right Away
Immediately after picking up, most hoods need a burst of width so the fabric can wrap around the head instead of the neck. A common approach is to increase evenly across the first row or two — figure roughly 20 to 40 percent more stitches than your neckline pickup count, more for adult sizes and less for children's — spread out so the increases don't cluster in one spot and distort the fabric.
Shape the Curve at the Back
After that initial widening, many hoods use short rows to build the curved dome at the crown, working a wrap-and-turn (or German short row) sequence centered on the back-of-neck stitches. Shortening by a stitch or two per row for the first half, then lengthening back out for the second half, coaxes the fabric into a rounded shape that follows the back of the head rather than sitting as a flat rectangle. If your pattern skips short rows and just has you knit straight up, that's fine too — it produces a slightly boxier hood that many knitters still find perfectly comfortable, especially with the drawstring cinching it in at the face.
Get the Depth Right
Depth (from the neckline to the top of the head) matters more than most new hood-knitters expect. As a rough guide:
- Toddler sizes: around 9 inches
- Kids and teens: around 10 inches
- Small to average adults: around 11 inches
- Larger adults or an oversized, slouchy look: 12 inches or more
Try the hood on (or hold it against the wearer) before binding off or closing the top — it's far easier to add a few more rows now than to unpick a grafted seam later.
Step 3: Close the Top
Once you've reached your target depth, it's time to join the two halves of the hood together. You have three main options, from most to least invisible:
- Kitchener stitch (grafting): Divide the live stitches evenly onto two needles and graft them together with a threaded tapestry needle, mimicking a row of knitting. This produces a completely seamless, flexible join with no ridge — ideal for a hood, since there's no bulky seam pressing against the top of the head.
- Three-needle bind-off: Fold the work in half with stitches on two needles, then use a third needle to knit corresponding stitches together and bind them off. This is faster and sturdier than grafting but leaves a visible ridge on the inside (or outside, if worked from the right side) of the hood.
- Bind off and seam: Bind off both sets of stitches separately and sew them together afterward. This is the bulkiest option and generally only worth using if you didn't leave stitches live.
For most sweater hoods, Kitchener stitch is worth the extra few minutes — it's the difference between a hood that feels smooth against the head and one with a seam you notice all day.
Step 4: Finish the Face Opening
The raw edge around the face is the last thing to address, and it matters both for looks and for keeping the edge from curling or stretching out of shape.
- Ribbing or garter border: Pick up stitches around the face opening and work a few rows or rounds of 1x1 or 2x2 ribbing, then bind off in pattern. This is simple and matches most sweater trims.
- I-cord edging: Cast on 2 to 4 extra stitches, then work an applied i-cord by knitting those stitches together with one live stitch from the hood edge at a time, sliding the stitches back to the left needle between rows. This wraps the opening in a neat, cord-like trim that resists curling and adds a bit of structure.
- Drawstring channel: If you want a cinchable hood, work a small eyelet row a short distance in from the face edge (a simple yarn-over, k2tog pattern spaced every few stitches works well), or fold over a section of the border and sew it down to create a casing. Thread cord or I-cord through the eyelets or channel afterward, and finish the ends with a bead or knot so the drawstring can't slip back inside.
Block the finished hood gently before adding the drawstring, easing it into a rounded shape rather than a flat triangle — a quick steam or damp block helps the increases and short rows relax into their intended curve.
With the neckline picked up, the depth and width shaped to fit, the top closed neatly, and the face edge finished, you've got a genuinely well-constructed hood — not just a flap of fabric sewn on, but a piece that was shaped to actually sit on a head. It's a technique worth adding to your toolkit; once you've done it once, you'll find yourself eyeing plain pullover patterns and thinking about how easily you could hood them.
