Iris 3 Piece Baby Set - Knitting Pattern For Babies in Tahki Yarns Hatteras by Tahki Yarns

Iris 3-Piece Baby Set – Knitting Pattern for Babies in Tahki Yarns Hatteras by Adventure Du Jour Designs

The Iris 3-Piece Baby Set is a charming and cohesive collection of handknitted baby items designed by Adventure Du Jour Designs and worked in Tahki Yarns Hatteras, a 100% organic cotton chunky-weight yarn. The set includes a large square blanket, a baby cardigan, and a baby hat, all unified by a coordinated two-color stripe palette. Rated intermediate in difficulty, this pattern is well-suited to knitters who are comfortable with basic shaping, stripe sequences, and working flat on straight and circular needles.

About the Yarn: Tahki Yarns Hatteras

Tahki Yarns Hatteras is a 100% organic cotton yarn, available in 3.5 oz / 100g skeins with approximately 109 yards / 100 meters per skein. Its chunky weight makes it ideal for baby items that knit up quickly while remaining soft and breathable against delicate skin. The pattern uses two colors throughout the set: #09 dusty violet (A) and #14 fog (B), a soft muted pairing that gives the finished pieces a gentle, modern aesthetic.

All three pieces are worked on size 10 (6 mm) needles, which is the standard recommended needle size for this yarn weight. The blanket uses a 32-inch / 80 cm circular needle to accommodate the large stitch count, while the hat and cardigan are worked on straight needles and a set of double-pointed needles (DPNs) for the sleeves. A size J/10 (6 mm) crochet hook is also called for in the hat and cardigan construction, likely for finishing or edging details.

The Blanket

The blanket is a one-size design measuring a generous 30 inches by 30 inches / 75 cm x 75 cm square, making it a practical and beautiful size for a stroller, crib, or play mat. It is worked flat on a long circular needle to manage the width of the fabric comfortably. The design incorporates stripe patterning using both colorways — #09 dusty violet and #14 fog — creating a visually appealing rhythm across the fabric. The blanket requires 4 balls of dusty violet (A) and 3 balls of fog (B), reflecting the dominant use of the violet tone in the stripe sequence.

Working a large blanket flat on circular needles is a common and practical technique that allows the knitter to spread the stitches across the cable, reducing strain on the wrists and making it easier to manage the growing fabric. Stitch markers are recommended to help track pattern repeats or stripe sections.

The Baby Hat

The Iris baby hat is sized to fit four head circumferences: 15½ (16½, 18, 19) inches / 39.5 (42, 45.5, 48.5) cm, corresponding to ages 3–6 months, 6–12 months, 12–18 months, and 18–24 months. Like the blanket, the hat features stripe work in the two coordinating Hatteras colors. It is worked using straight needles and likely transitioned to double-pointed needles for crown shaping, which is a standard technique for top-down or flat-knitted hats that are seamed. Removable stitch markers assist with shaping decreases.

The hat uses 1 ball of fog (A) and 2–3 balls of dusty violet (B) depending on the size, though yarn requirements are shared across the hat and cardigan together, making efficient use of each skein.

The Baby Cardigan

The Iris baby cardigan is the most technically involved piece in the set, sized to fit chest measurements of 18½ (21, 23, 25) inches / 47 (53.5, 58.5, 63.5) cm across the same four age ranges. The body length ranges from 6 to 9 inches / 15 to 23 cm depending on the size
