Valley Yarns Polygonia Knitting Pattern

Valley Yarns Polygonia Baby Onesie: Pattern Summary

What Is Being Made

The Polygonia is a knitted baby onesie designed by Julie Turjoman for Valley Yarns. This garment is crafted for active infants and features practical construction details including a buttoning inseam along the legs and a front neck placket for convenient dressing and undressing. The onesie includes stylish back pockets and short legs, making it ideal for babies during active play. The design is generously sized to accommodate growth and extended wear across multiple size ranges.

Sizes and Finished Measurements

The Polygonia is available in four size options: 0-3 months, 3-6 months, 6-12 months, and 12-18 months. Finished chest measurements range from 19½ inches for the smallest size to 24½ inches for the largest size. Length measurements span from 16½ inches to 20½ inches, allowing for extended wear as babies grow.

Techniques Used

This pattern employs several fundamental knitting techniques suitable for advanced beginners. The onesie is constructed using a bottom-up building method, with the garment worked in two separate pieces—front and back—that are later joined. Decrease shaping is incorporated throughout to create a tailored, fitted silhouette. The construction features buttonhole placement along the leg inseam and front neck opening, with buttons serving as functional closures for easy on-and-off dressing. The Long-Tail cast-on method is used to begin the leg sections, providing a professional and elastic foundation edge.

Stitches and Stitch Patterns

The Polygonia features a striking Baby Cable stitch pattern that appears in multiple sections of the garment. The leg ribbing is worked entirely in the Baby Cable pattern, creating visual interest and texture from the cuff upward. The upper body continues this same Baby Cable stitch pattern, maintaining design cohesion throughout the piece. Armhole and neck edging are finished with k2/p2 rib (knit 2, purl 2 ribbing), providing elasticity and a polished edge. The main body sections are worked in stockinette stitch, the fundamental knit stitch that creates a smooth, classic fabric.

Materials and Yarn Requirements

The pattern calls for Valley Yarns Haydenville DK weight yarn, a practical choice for baby garments. Haydenville DK is composed of 60% Superwash Merino Wool and 40% Acrylic Microfiber, making it machine washable and gentle on delicate baby skin. Each skein contains 50 grams and yields 136 yards. Yarn requirements range from 3 skeins for the smallest sizes (0-3 months and 3-6 months) to 4 skeins for the larger sizes (6-12 months and 12-18 months). The recommended color shown in the pattern is Color 10 Red.

Needles and Tools

The pattern requires US size 5 (3.75 mm) needles as the primary working needles to achieve proper gauge. US size 4 (3.50 mm) 16-inch circular needles and double-pointed needles (dpn) are used for ribbed sections and smaller circumference areas. Additional materials include stitch markers for tracking pattern repeats, a tapestry needle for seaming and finishing, and 10 buttons at ½ inch diameter for the inseam and neck placket closures.

Gauge and Construction Notes

The pattern specifies a gauge of 24 stitches and 32 rows over 4 inches in stockinette stitch using the larger needles, measured after blocking. Achieving proper gauge is essential for the garment to fit correctly across all size ranges. The onesie construction begins with the back legs, where stitches are cast on using the Long-Tail method and worked in Baby Cable Rib for 2 inches before increases are evenly distributed across a wrong-side row. Stitches are then transferred to holders as pieces are completed, allowing for later assembly. Optional back pockets are sewn onto the finished onesie during the final assembly stage, adding both function and style to the design.

Skill Level

The Polygonia is rated as Advanced Beginner difficulty, making it suitable for knitters who have mastered basic techniques and are ready to tackle garment construction with shaping, multiple stitch patterns, and button placement.
