Baby Sleep Sack Knitting Pattern – Schachenmayr Baby Smiles Merino Wool (S8641)

This free downloadable PDF pattern (S8641) from Schachenmayr provides complete instructions for knitting a cosy baby sleep sack with a hood, designed to keep infants warm and comfortable through the night. The finished piece features a structured body, an integrated hood, a ribbed cuff at the hem, a button placket, and a clever underflap opening — making it both practical and beautifully detailed for a handmade baby gift or nursery essential.

What Is Being Made

The pattern produces a full baby sleep sack (Schlafsack) knitted in two main pieces — a back panel and a front panel — which are then joined together. The sleep sack includes:

• A structured body worked in a combination of textured stitch patterns
• An integrated hood shaped by gradual decreases at the top of the back piece
• A ribbed cuff border (Bündchen) at the lower hem, worked in 2×2 rib for a neat, stretchy finish
• A button placket (Knopflochblende) with four white buttons, approximately 28 mm in diameter, for easy dressing and undressing
• An underflap (Untertritt) — a practical overlapping section that adds warmth and prevents draughts at the front opening

The total finished height of the sleep sack is approximately 73 cm, making it a generous size suitable for young babies and infants.

Materials Used

The pattern calls for Schachenmayr Baby Smiles Merino Wool, a soft 4-ply weight yarn, in White (colour 01001). A total of 425 g of this yarn is required. Merino wool is a popular choice for baby knitwear because of its exceptional softness against delicate skin, its natural temperature-regulating properties, and its gentle elasticity, which helps the finished garment hold its shape over time.

• Yarn: Schachenmayr Baby Smiles Merino Wool, 425 g, White (Fb 01001)
• Knitting needles: Milward size 3.5 mm
• Crochet hook: Milward size 2.5 mm (used for finishing details)
• Buttons: 4 white buttons, approximately 28 mm in diameter

Techniques Used

This pattern is rated as a knitting project with an additional crochet element for finishing. It is well suited to knitters with some experience of working textured stitch patterns and simple shaping. Key techniques include:

• Casting on and casting off — including mid-row cast-ons used to create the underflap and button placket sections
• Increasing and decreasing — gradual shaping is used at the sides of the body and extensively at the top of the back piece to form the curved hood
• Working in pattern — maintaining multiple stitch patterns simultaneously across the width of the fabric
• Crochet finishing — a 2.5 mm crochet hook is used for edging or joining, adding a neat professional finish to the completed garment
• Button placket construction — picking up stitches along a selvedge edge to create the button and buttonhole bands

Stitches Used

The sleep sack is worked in a combination of three stitch patterns that run side by side across the body, creating a visually interesting and textured fabric:

• Grundmuster (main pattern / cable panel combination): The body is divided into sections — 12 stitches of rib pattern, 12 stitches of cable pattern, and 12 stitches of rib pattern — flanked by selvedge stitches on each side. The gauge for this main pattern is approximately 34 stitches and 36 rows to 10 cm × 10 cm.
