Sirdar Snuggly Peekaboo DK Pattern 4487 – Sweater and T-Bag Hat for Babies and Children

This downloadable PDF knitting pattern from Sirdar presents two charming designs for babies and young children: a classic pullover Sweater and a fun T-Bag Hat. Both are worked in Sirdar Snuggly Peekaboo DK, a self-striping or colour-effect double knitting yarn that adds visual interest without requiring any colour changes by the knitter. The pattern is numbered 4487 and is part of the Sirdar Snuggly range, designed with young wearers in mind — soft, practical, and appealing.

Who This Pattern Is For

The pattern covers a wide range of sizes, making it a versatile choice for gift knitters and parents alike. The Sweater is sized from birth to 7 years, fitting chest measurements of 41 cm (16 in) up to 66 cm (26 in), with actual garment measurements ranging from 45 cm to 70 cm. The T-Bag Hat is designed to fit an average baby's or child's head for each corresponding age group. This broad size range means the pattern offers excellent long-term value as a go-to design for handmade children's gifts.

The Sweater

Design and Construction

The sweater is a straightforward, wearable pullover constructed in separate pieces — back, front, and sleeves — which are then seamed together. It features a neat ribbed border and a structured body worked in a defined stitch pattern. Shoulder shaping is included, with stitches cast off at the beginning of rows to create a clean, fitted shoulder line. A stitch holder is used during construction, most likely to hold neckline stitches while other sections are completed, which is a standard technique in children's sweater knitting that allows for a tidy, finished neckline.

The sleeve length is noted as adjustable, ranging from 15 cm (6 in) for the smallest size up to 33 cm (13 in) for the largest, giving knitters the flexibility to customise the fit. Full length of the sweater ranges from 24 cm (9½ in) for newborns up to 46 cm (18 in) for the 6–7 year size.

Stitches and Techniques Used

• Knit stitch (k) — used throughout the pattern body rows
• Purl stitch (p) — used in pattern rows and ribbing
• Ribbing — worked on the smaller 3¼mm needles to create neat, stretchy borders at the cuffs and lower edges
• Stocking stitch or textured pattern — the main body fabric is worked on 4mm needles following a set row repeat
• Make 1 (m1) — an increase technique where a loop is picked up between the last and next stitch and worked into the back of the loop, creating a neat, virtually invisible increase used for sleeve shaping
• Knitting two stitches together (tog) — a standard decrease used in shaping
• Shoulder shaping — achieved by casting off stitches at the beginning of rows
• Stitch holder usage — stitches are placed on hold for later finishing, a key technique in structured garment knitting

Needle Sizes

• 3¼mm needles (UK 10 / USA 3) — used for ribbed borders and welts
• 4mm needles (UK 8 / USA 6) — used for the main body and sleeves

The T-Bag Hat

Design and Construction

The T-Bag Hat is a playful accessory that pairs perfectly with the sweater. The name suggests a gathered or tied top — a style where the hat is knitted as a tube or rectangle and the top is cinched or tied to create a distinctive bag-like or topknot shape, reminiscent of a tea bag. This is a popular and endearing style for baby hats, giving a soft, slouchy silhouette that is both practical and adorable. It is sized to fit an average baby's or child's head for
