Polygonia Onesie – Baby Knitting Pattern by Julie Turjoman for Valley Yarns

The Polygonia Onesie, pattern number 1088, is an original baby knitwear design by Julie Turjoman, published by Valley Yarns. This downloadable PDF pattern produces a charming, practical, and stylish one-piece garment sized for infants from 0–3 months through 12–18 months. The sample shown in the pattern is knitted in Size 6–12 months. Finished chest measurements range from 19½ to 24½ inches, and finished lengths range from 16½ to 20½ inches, making it generously proportioned for extended wear and active play.

What Is Being Made

The Polygonia Onesie is a bottom-up, two-piece knitted baby bodysuit — worked as a separate front and back — that is then seamed and finished together. Key practical features include:

• Buttoning inseam along the legs for easy diaper changes
• Front neck placket with buttons for simple on and off dressing
• Short legs suited to active infant movement
• Optional back pockets sewn on during finishing for a stylish, functional touch

The garment is described as generously sized to allow for long wear and freedom of movement, making it an ideal everyday piece for babies at the crawling and early walking stages.

Construction Technique

The onesie is constructed using a bottom-up method, beginning at the cast-on edge of each leg and working upward. The two pieces — front and back — are knitted separately and then joined. This approach gives knitters clear, manageable sections to work through rather than one large, complex piece. Decrease shaping is used throughout to create a tailored, fitted silhouette appropriate for a growing infant's body. The Long-Tail Cast-On method is specified for starting each leg, a technique well-suited to ribbing as it produces a neat, elastic edge.

The optional pockets are worked separately and sewn onto the back of the onesie during the finishing stage, adding a decorative and functional element without complicating the main construction.

Stitches and Stitch Patterns Used

The Polygonia Onesie features a combination of stitch patterns that balance visual interest with wearability:

• Baby Cable Rib – The signature stitch of this pattern, used on the leg ribbing sections and carried through to the upper body. Baby cables are a classic knitting technique in which a small group of stitches — typically two or four — are crossed over one another at regular intervals to create a twisted, rope-like column. They add texture and visual interest while remaining simple enough for an advanced beginner to execute confidently.
• Stockinette Stitch – Used for the main body of the legs after the ribbing section, providing a smooth, classic fabric. Gauge is measured in stockinette: 24 stitches and 32 rows to 4 inches, blocked, on the larger needle size.
• K2/P2 Rib – Applied to the armhole and neck edgings, this standard two-by-two ribbing creates a stretchy, tidy border that lies flat and frames the neckline and armholes neatly.
• Buttonholes – Worked into the neck placket and leg inseam to accommodate the 10 half-inch buttons required to complete the garment.

Techniques Used

• Bottom-up construction – Knitting begins at the lower edge of each leg and progresses upward toward the body
• Long-Tail Cast-On – Specified for starting each leg piece, producing a firm yet elastic foundation row
• Cable knitting – Baby Cable pattern worked throughout the leg ribbing and upper body sections
• Increase shaping – Stitches are increased evenly across a wrong-side row after the initial ribbing to transition into the wider body fabric
• Decrease shaping – Used to create the tailored fit of the ones
