Eyelet Hat in Loopy Mango Summer Cotton — Pattern Summary

This downloadable PDF pattern from Loopy Mango guides knitters through creating a charming, lightweight knitted hat featuring a delicate eyelet lace detail worked into the body of the hat. Designed with warm-weather wear in mind, the Eyelet Hat in Summer Yarn is an ideal project for anyone looking to practice basic lace techniques while producing a functional, stylish accessory. The pattern is rated Beginner level, making it an approachable introduction to yarn-over lace patterning for newer knitters.

What Is Being Made

The finished project is a knitted beanie-style hat worked entirely in the round, available in five sizes to fit a wide range of wearers from infants to adults. The five sizes and their approximate finished measurements are:

• Baby (6–18 months): 12.5'' circumference, 6'' height
• Toddler (1–3 years): 14'' circumference, 6.5'' height
• Child (4–8 years): 16'' circumference, 7'' height
• Tween (9–12 years): 18.5'' circumference, 7.5'' height
• Adult: 19.5'' circumference, 8'' height

The hat has a smooth stockinette body punctuated by multiple rounds of eyelet lace patterning that create an airy, decorative texture — perfect for a cotton summer hat that needs both breathability and visual interest.

Techniques Used

The pattern is worked in the round on circular needles from the cast-on edge up to the crown, which is closed by drawing the yarn through the remaining live stitches and cinching — a clean and simple finishing method that avoids the need for seaming. The eyelet sections are created through a combination of yarn overs and k2tog decreases, which keep the stitch count consistent while forming the characteristic open, lacy holes. Crown shaping is achieved through paired k2tog decrease rounds that rapidly reduce stitches to close the top of the hat neatly.

Knitting in the round is a foundational technique in hat construction — it eliminates the need for seams and allows the knitter to always work on the right side of the fabric, making stitch patterns easier to read and execute. For beginners, this pattern is an excellent way to become comfortable with circular needle knitting while also taking a first step into simple lace construction.

Stitches Used

• Knit (K): The primary stitch used throughout the hat body, forming the smooth stockinette fabric
• Purl (P): Listed in the abbreviations for reference
• Yarn Over (YO): Creates the decorative eyelet holes in the lace sections
• Knit Two Together (K2TOG): A right-leaning decrease used both in the eyelet pattern (to compensate for yarn overs and maintain stitch count) and in the crown shaping rounds to reduce stitches
• Stockinette stitch in the round: All knit rounds worked in the round produce the smooth, classic stockinette fabric that forms the majority of the hat

The gauge for this pattern is 13.5 stitches and 20 rows over 4 inches in stockinette stitch knitted in the round, which is important to check before beginning to ensure accurate sizing across the five available sizes.

Materials

The pattern calls for one ball of Loopy Mango Summer Yarn, a chunky weight, 100% cotton yarn that comes in 100g / 3.5 oz balls with approximately 90 yards (82 meters) per ball. Cotton is a natural fiber well suited to warm-weather accessories — it is breathable, soft against the skin, and holds stitch definition beautifully, making the eyelet details crisp and visible in the finished hat.

The recommended needles are US size 10 (6 mm) circular knitting needles, 16 inches (40 cm) in length — a standard length for knitting adult and child hats in the round. Loopy Mango also
