Tahki Yarns Cosmos Knitting Pattern

Tahki Yarns Cosmos Knitted Sweater

What is Being Made

The Cosmos pattern is a knitted pullover sweater designed by Nancy Camposano. This garment is available in five sizes ranging from Small to 2X, with finished bust measurements from 38½ inches (98 cm) to 50½ inches (128.5 cm) and lengths from 20 inches (51 cm) to 24 inches (61 cm). The sweater features a classic crew neckline and is constructed using a seamed, bottom-up building method, making it an ideal project for knitters seeking a straightforward yet polished finished garment.

Construction Techniques

This sweater is worked flat on straight needles rather than in the round, allowing knitters to work each piece separately before assembly. The garment uses a bottom-up construction method, meaning the knitter begins at the lower edge of the back and front panels, then works upward to the shoulders. All pieces are subsequently seamed together using a yarn needle, creating clean, professional-looking seams along the sides and sleeve caps. This traditional approach provides excellent control over fit and allows for straightforward shaping throughout the project.

Stitches and Stitch Patterns

The Cosmos pattern employs two primary stitch patterns. Seed stitch is used for the ribbed cuffs and lower edges, creating a textured, reversible fabric that measures 2 inches (5 cm) in depth. Seed stitch is worked by alternating knit and purl stitches across each row, then offsetting these stitches on subsequent rows to create the characteristic bumpy texture.

Sand Rib serves as the main stitch pattern for the body and sleeves. This textured stitch is worked over a multiple of 2 stitches and repeats over 4 rows. The pattern alternates between knit rows and purl rows in a specific sequence: Row 1 (right side) is knit entirely, Row 2 (wrong side) is purled entirely, Row 3 combines knit and purl stitches in alternation, and Row 4 is purled. This creates a subtle ribbed texture that provides gentle stretch and visual interest while remaining accessible for knitters of all skill levels.

Shaping and Design Details

The sweater incorporates strategic increases and decreases to achieve proper fit. Sleeve shaping begins after the initial seed stitch cuff and involves multiple increase sequences worked at regular intervals—every 8 rows, every 6 rows, and every 4 rows depending on size—to gradually expand the sleeve width. Armhole shaping is accomplished through bind-offs at the beginning of rows, followed by single-stitch decreases worked at the side edges. Neckline shaping on the front piece uses single-stitch decreases worked on right-side rows to create a gradual neck opening.

Materials and Yarn Specifications

The Cosmos pattern calls for Tahki Yarns Jupiter, a blend of 55% cotton and 45% polyester. This fiber composition creates a garment with excellent breathability and comfort, making it suitable for warm-weather wear. The yarn is provided in 1.75-ounce (50-gram) balls, each containing 136.7 yards (125 meters). Depending on size, the project requires 7 to 11 balls of yarn in color #316 lilac, providing sufficient yardage for all pattern pieces and finishing.

Needles and Notions

The pattern requires two sets of straight needles: size 7 (4.5mm) needles for the main fabric and size 5 (3.75mm) needles for the ribbed edges. The smaller needle size creates a tighter gauge in the cuff and lower-edge ribbing, ensuring these areas remain elastic and structured. Additionally, a size 5 (3.75mm) circular needle measuring 16 inches (40 cm) is needed for the neckband. Essential notions include stitch markers for tracking pattern repeats and shaping points, stitch holders for securing stitches during construction, and a yarn needle for seaming and weaving in ends.

Gauge and Fit

The pattern specifies a gauge of 20 stitches and 29 rows equaling 4 inches (10 cm) when working the Sand Rib stitch pattern on the larger needles. Achieving proper gauge is essential for obtaining the correct finished measurements and overall fit. Knitters are advised to knit a gauge swatch using the larger needles and Sand Rib pattern before beginning the project, adjusting needle size as needed to match the specified gauge.
