Making a Garter Stitch Baby Hat With Ear Flaps
A small knitted hat with ear flaps is a thoughtful handmade gift and a practical way to use soft, washable yarn. Garter stitch keeps the fabric warm, flexible, and pleasantly squishy, while the flaps cover the ears and create a secure fit for a wiggly baby.
This pattern is worked flat with simple increases and decreases, so it suits knitters who are comfortable with the knit stitch but are still developing confidence with shaping. The finished hat is seamed at the back, and knitted or braided ties keep the ear flaps in place.

Choose Yarn, Needles, And Measurements
Use a soft worsted-weight or aran-weight yarn made from machine-washable wool, superwash wool, cotton, acrylic, or a gentle blend. Baby garments benefit from yarn that feels smooth against the skin and can withstand frequent washing. Avoid fuzzy fibers that may shed near a baby’s face, and check the yarn label for care instructions before beginning.
A 4.5 mm or 5 mm pair of straight needles works well for this project. The exact needle size depends on your yarn and tension. Aim for approximately 18 stitches and 36 rows in 10 cm of garter stitch. Garter stitch has a distinctive horizontal ridge on both sides because every row is knitted.
Measure the baby’s head if possible. A snug hat should have around 1–2 cm of negative ease, meaning the finished circumference is slightly smaller than the head measurement. This helps the fabric stay in place without making the hat tight. The sample instructions below suit a small baby size, with adjustments explained later.
Knit The Ear Flaps First
Cast on 4 stitches for the first ear flap. Knit one row, then increase one stitch at the beginning and end of every right-side row until you have 16 stitches. A simple knit-front-and-back increase works well, although a lifted increase can create a neater edge.
Continue knitting every row until the flap measures about 4 cm from its cast-on point. Leave the stitches on the needle or transfer them to a stitch holder. Make a second ear flap in exactly the same way. Matching row counts are useful because they allow the hat to sit evenly around the head.
To join the pieces, knit across the first ear flap, cast on 16 stitches for the front of the hat, knit across the second ear flap, and cast on another 16 stitches for the back. You now have 64 stitches. Place a marker at each join if you want clear reference points while working the crown.
Build The Hat In Garter Stitch
Knit every row across the 64 stitches. The ear flaps will sit at opposite sides, while the cast-on sections form the forehead and back of the hat. Continue until the fabric from the flap join measures approximately 9–10 cm, or until the hat reaches just above the baby’s crown.
Keep the edges relaxed. Pulling the first stitch too tightly can make the side seam stiff and may prevent the hat from stretching comfortably. If your edge stitches look loose, slip the first stitch purlwise with the yarn held at the back, then knit the remaining stitches. Use the same edge method consistently throughout the main body.
The garter ridges make it easy to count rows and identify the fabric’s right and wrong sides, although both sides look the same. For a longer hat, add several plain rows before beginning the crown decreases. For a closer-fitting cap, start shaping sooner.
Shape The Crown Evenly
Crown shaping can be kept simple by reducing eight stitches on every other row. On the first decrease row, knit 6 stitches, knit 2 together, and repeat across the row. Knit the next row without decreases. On the following decrease row, knit 5 stitches, knit 2 together, and repeat the sequence.
Continue in this way, reducing the number of plain stitches between decreases each time. The decrease rows will progress approximately as follows: knit 4, knit 2 together; knit 3, knit 2 together; knit 2, knit 2 together; then knit 1, knit 2 together. Finish with knit 2 together across the remaining stitches.
| Baby Size | Approximate Head Circumference | Cast-On Sections | Suggested Body Length |
|---|---|---|---|
| Newborn | 33–35 cm | 12 stitches between flaps | 8–9 cm |
| 0–3 months | 35–38 cm | 16 stitches between flaps | 9–10 cm |
| 3–6 months | 38–42 cm | 20 stitches between flaps | 10–11 cm |
After the final decrease row, cut the yarn while leaving a 20 cm tail. Thread the tail through the remaining stitches, pull gently to close the crown, and secure it on the inside. Avoid drawing the opening too tightly, since a slightly rounded crown is more comfortable and easier to seam.
Finish The Seams And Ties
Fold the hat so the ear flaps align, with the wrong side facing outward. Use mattress stitch or a neat whip stitch to join the back seam. Work through the outermost loops without pulling too firmly. The seam should lie flat and retain the stretch of the garter fabric.
For each tie, attach three strands of yarn measuring about 45 cm at the lower point of an ear flap. Braid the strands, twist them, or make a narrow knitted cord. Secure the end with a small knot and trim the tails evenly. Keep the ties short enough to avoid loose loops, and inspect them regularly as the baby grows.
Weave in all remaining ends securely. Wash the hat according to the yarn label, shape it over a small bowl or rolled towel, and let it dry flat. Blocking smooths the garter ridges and helps the ear flaps settle into their intended position.
Adapt The Design With Confidence
Color changes can add character without complicating the construction. Work the main hat in a calm neutral shade and use a contrasting color for the ear flaps, ties, or final crown section. Narrow stripes every four or six rows are especially effective in garter stitch because the ridges make color transitions clear.
Hand-dyed yarn can create beautiful shifts across a small project, but skeins may vary in length and color distribution. Before casting on, explore these hand-dyed yarn tips so the color changes remain balanced and the fabric behaves predictably.
For a larger size, add equal numbers of stitches to the front and back cast-on sections rather than changing the ear flap width. Each additional 4–5 stitches adds roughly 2.5 cm to the circumference at the stated gauge. Always make a small swatch first, since a difference of only two stitches per 10 cm can significantly alter the fit.
- Measure the baby’s head and compare it with the blocked fabric before sewing the seam.
- Use a smooth, washable yarn with no loose fibers or decorative texture.
- Mark the ear-flap joins so the crown decreases stay evenly distributed.
- Keep ties short, secure, and free from long loops.
- Wash and dry the finished hat before gifting it.
Care For A Handmade Baby Hat
Garter stitch is durable, but its ridges can stretch if the hat is pulled sharply when wet. Wash it gently in lukewarm water with a mild detergent, press out excess moisture inside a towel, and dry it flat. Reshape the crown and ear flaps while damp instead of hanging the hat, which can lengthen the fabric.
A hand-knit hat should be checked before every use. Look for loose ties, weakened seams, or areas where the yarn has become damaged. If the hat includes a pom-pom or other embellishment, make sure it is firmly attached and avoid using detachable decorations for very young babies.
This project also makes a useful practice piece for learning gauge, increases, decreases, seaming, and basic finishing. Once the construction feels familiar, the same approach can be adapted into a striped winter cap, a newborn photography bonnet, or a coordinating set with booties and a small garter stitch blanket.
Gather a soft yarn, make a quick gauge swatch, and begin with the first ear flap. The simple rhythm of knitting every row lets the fabric grow steadily while the shaping provides enough interest to keep the project engaging. A carefully finished hat becomes a warm, personal gift that can be worn, washed, and treasured.
