Mariner Polo in Sirdar Snuggly DK – Pattern Summary

The Mariner Polo (Design No. 5593) is a charming baby knitting pattern from Sirdar, part of their Petit Breton collection — a breezy range inspired by nautical Breton stripes and first holidays by the French seaside. This downloadable PDF pattern produces a sweet Poncho Top designed for babies and toddlers aged 0 to 24 months, making it an ideal handmade gift or wardrobe staple for little ones in their earliest years.

What Is Being Made

The finished garment is a baby poncho-style top worked in a classic two-colour stripe design. It is sized across six age brackets — 0–3 months, 3–6 months, 6–9 months, 9–12 months, 12–18 months, and 18–24 months — with chest measurements ranging from 42 cm (16½ inches) to 53 cm (21 inches) and full lengths from 26 cm to 37 cm. Short sleeves of a consistent 5 cm (2 inches) feature across all sizes, giving the top a relaxed, easy-to-wear silhouette perfect for layering over bodysuits or wearing alone in warmer weather.

The nautical colour palette uses Yarn A in shade 412 Soldier Blue and Yarn B in shade 303 Cream, echoing the timeless Breton stripe aesthetic that has influenced children's fashion for generations. Additional colourway inspiration shown in the collection includes 242 Flamenco, 216 Sky, 224 Light Navy, and 446 Rice Pud, offering knitters flexibility to personalise their makes.

Yarn and Materials

This pattern is specifically designed for use with Sirdar Snuggly DK, Britain's best-loved baby yarn, which has been trusted by knitters for generations. Sirdar Snuggly DK is a 50g double knitting weight yarn (yarn code F075) celebrated for its exceptional softness and its ability to stay gentle and smooth wash after wash — an essential quality for garments worn against a baby's delicate skin. The yarn is available in a wide range of shades from soft neutrals and classic pastels to modern brights.

• Yarn A (shade 412 Soldier Blue): 2 balls for sizes 0–3 months through 9–12 months; 3 balls for sizes 12–18 months and 18–24 months
• Yarn B (shade 303 Cream): 1 ball across all sizes

In addition to yarn, knitters will need:

• 1 pair of 4mm (UK8 / USA6) knitting needles — used for the main body sections
• 1 pair of 3¼mm (UK10) knitting needles — typically used for ribbing and neckline finishing

Techniques and Stitches Used

This pattern is rated Easy by Sirdar, making it an excellent project for beginner knitters who are comfortable with basic knitting skills and ready to explore simple colourwork. Sirdar triple-checks all their patterns to guarantee success when worked in the recommended Sirdar yarns, giving newer knitters added confidence.

The construction of the poncho top draws on foundational knitting techniques well-suited to those building their skills:

• Double knitting (DK) weight knitting — working with a medium-light yarn weight that knits up at a satisfying pace while producing a fabric with excellent stitch definition
• Two-colour stripe knitting — alternating between Soldier Blue and Cream to create the signature Breton-inspired stripe pattern; this technique involves carrying or joining yarn at the edges of rows, a manageable skill for beginners
• Ribbing — typically used at cuffs, hems, and necklines to create a neat, elasticated finish that helps garments retain their shape and sit comfortably on a baby
• Stocking stitch — the classic knit-one-row, purl-one-row construction that forms the
