Sirdar Snuggly Peekaboo DK Pattern 4457 – Sweater and Tank Top for Babies and Children

This official Sirdar pattern 4457 is a downloadable PDF offering two classic knitwear designs for babies and young children: a long-sleeved sweater and a sleeveless tank top. Both garments are rated Easy Knit, making this an ideal project for beginner knitters who want to create beautiful, practical pieces for little ones aged birth to 7 years. The pattern is worked in Sirdar Snuggly Peekaboo DK, a yarn specifically designed with babies and children in mind, and covers six size options to suit a wide range of ages and chest measurements.

Design Overview and Sizing

The pattern includes two distinct garments that share the same yarn and basic construction approach, making it easy to knit both as a coordinating set or to choose whichever style suits the occasion.

The Sweater

The sweater is a traditional, comfortable pullover featuring long sleeves. It is designed to fit chest sizes ranging from 41 cm (16 in) for 0–6 months up to 66 cm (26 in) for 6–7 years, with actual garment measurements providing a little ease for comfortable wear. Full lengths range from 24 cm (9½ in) for the smallest size up to 48 cm (19 in) for the largest. Sleeve lengths are noted as adjustable, ranging from 15 cm (6 in) to 33 cm (13 in), allowing knitters to customise the fit further. The sweater is worked in Sirdar Snuggly Peekaboo DK shade 101, requiring between 2 and 5 balls of 50g yarn depending on the size being made.

The Tank Top

The tank top is a sleeveless version of the same classic silhouette, perfect as a layering piece or a standalone garment in warmer weather. It follows the same six size range as the sweater, with full lengths from 22 cm (8¾ in) to 46 cm (18 in). The tank top is worked in Sirdar Snuggly Peekaboo DK shade 104 and requires between 1 and 4 balls of 50g yarn, making it a particularly economical and quick project for the smaller sizes.

Techniques and Construction

Both garments are constructed using straightforward, traditional knitting techniques that are well-suited to beginner knitters. The construction follows a classic flat-knitting approach, with separate pieces worked and then seamed together. Key techniques referenced in the pattern include:

• Thumb cast-on method – used to begin the pieces, a reliable and beginner-friendly cast-on technique that creates a neat, elastic edge
• Ribbing – worked on the smaller 3¼mm needles to create neat, stretchy welts and cuffs that help the garments hold their shape
• Stocking stitch pattern – the main body fabric, described in the pattern as a two-row repeat of knit and purl rows, giving a smooth, classic finish
• Armhole shaping – simple decreasing is used to shape the armholes on both garments
• Stitch holders – used to hold stitches in reserve while other sections are worked, a standard technique for managing necklines and shoulder shaping
• Increasing and decreasing – used throughout for shaping sleeves and necklines

Stitches Used

The stitch vocabulary in this pattern is intentionally simple, keeping it accessible for those new to knitting. The stitches and stitch patterns used include:

• Knit stitch (k) – the most fundamental knitting stitch, used throughout
• Purl stitch (p) – worked on wrong-side rows to create the smooth stocking stitch fabric
• Stocking stitch – formed by alternating knit rows on the right side and purl rows on the wrong side; this is the primary pattern stitch for both garments
• Rib stitch –
