Two Designs in One Pattern

The PDF covers two distinct waistcoat designs, each worked in a different colourway of the same yarn base, allowing crafters to make a coordinating pair or choose their favourite version.

Waistcoat 1 – Baby Mint (Shade 853)

The first waistcoat is worked in Baby Bonus DK shade 853 Baby Mint, a soft, cool-toned pastel that is perfect for a fresh, classic baby look. This design requires just 1 ball of yarn across all sizes from 0–3 months through to 18–24 months, making it an economical and quick make.

Waistcoat 2 – Baby Peach (Shade 581)

The second waistcoat is crocheted in Baby Bonus DK shade 581 Baby Peach, a warm, gentle tone that suits a variety of skin tones and seasons. This version requires 1 ball for sizes 0–3 months through 12–18 months, and 2 balls for the larger 18–24 month size.

Sizing and Measurements

The pattern includes six sizes to cover the full range of the first two years of a baby's life. Finished chest measurements and full lengths are as follows:

• 0–3 months: 42 cm (16½") chest, 25 cm (9¾") full length
• 3–6 months: 46 cm (18") chest, 27 cm (10¾") full length
• 6–9 months: 50 cm (19¾") chest, 30 cm (11¾") full length
• 9–12 months: 52 cm (20½") chest, 32 cm (12½") full length
• 12–18 months: 54 cm (21¼") chest, 34 cm (13½") full length
• 18–24 months: 56 cm (22") chest, 36 cm (14") full length

The width measurement (which accounts for the finished blocked width of the garment pieces) ranges from 46 cm (18") at the smallest size up to 61 cm (24") at the largest, reflecting the ease built into the design for comfortable baby wear.

Techniques and Stitches Used

Both waistcoats are constructed using a Half Treble (htr) pattern stitch as the main fabric stitch. The half treble crochet — known in the US as the half double crochet (hdc) — creates a dense yet slightly stretchy fabric with a subtle horizontal texture, ideal for a structured baby garment that still has gentle give. It sits between a double crochet and a treble in height, producing a neat, even fabric that works up quickly.

As an intermediate-level crochet pattern, the waistcoats involve techniques beyond simple flat rectangles. Crocheters can expect to work:

• Half treble crochet as the primary stitch throughout the main body fabric
• Shaping through increases and decreases to form the armhole openings and neckline
• Garment construction involving separate front and back panels that are seamed together
• Tension management to achieve the correct gauge across multiple sizes

Working to the correct tension is essential for achieving the stated measurements. The specified tension is 16 stitches and 14 rows to 10 cm / 4 inches
