Y-Shaped Waistcoat in BC Garn Baby Alpaca – Pattern Summary (No. 2235BC)

Designed by Jytte Slente and published by BC Garn, the Y-Shaped Waistcoat (pattern number 2235BC) is a cleverly conceived knitted waistcoat that begins life as a long, wide scarf and is then folded, seamed, and shaped into a wearable garment. This free, downloadable PDF pattern is rated intermediate in difficulty and is a wonderful example of how a single knitted rectangle can be transformed into a versatile, elegant piece of knitwear with minimal finishing work.

What Is Being Made

The finished object is a knitted waistcoat — a sleeveless, body-covering garment — constructed from what is essentially a very long ribbed scarf. The scarf measures approximately 40 × 170 cm for size S/M and 45 × 198 cm for size L/XL. Once folded and seamed at the back and along the armhole lines, it becomes a fitted, stretchy waistcoat. One of the most appealing features of this design is its reversible, dual-wear functionality: worn one way, it creates a long, close-fitting waistcoat with the seam sitting at the mid back; turned upside down, the same garment becomes a shorter, looser waistcoat with a natural collar formed at the back of the neck. This Y-shaped construction is where the pattern gets its name.

Sizes

• S/M – scarf dimensions approximately 40 × 170 cm; uses 200 g of yarn
• L/XL – scarf dimensions approximately 45 × 198 cm; uses 250 g of yarn

Techniques Used

The construction method is refreshingly simple yet ingenious, making it an excellent project for knitters who are comfortable with basic techniques but want an interesting result without complex shaping or multiple pieces to seam together.

• Rectangular knitting: The entire garment is worked as a single, straight rectangle with no increases or decreases — the scarf is knitted from cast-on to cast-off without any shaping rows.
• Folding and seaming: The scarf is folded at its centre point so that the cast-on and cast-off edges meet. A seam is then worked from the fold edge upward for 16 cm (S/M) or 20 cm (L/XL) along the mid back.
• Armhole creation: Rather than knitting armholes into the fabric, they are formed during finishing. From the point where the back seam meets the centre fold, additional seams are sewn 16 cm (S/M) or 20 cm (L/XL) outward to the left and right, creating two armholes with a circumference of approximately 37 cm (S/M) or 39 cm (L/XL).
• Wet finishing / blocking: The completed waistcoat is rinsed and laid flat on a towel to dry, which is the recommended finishing method for the yarn used.
• Fastening: The front of the waistcoat is left open and secured with one horn buckle or scarf pin, adding a tactile, natural accessory detail that complements the alpaca fibre beautifully.

Stitches Used

The entire garment is worked in a single stitch pattern throughout, making it ideal for knitters who want to focus on the meditative rhythm of a repetitive stitch while still producing a sophisticated result.

• Rib stitch (K3, P3): The body of the waistcoat is worked in a knit 3, purl 3 rib pattern. This is a classic, deeply textured rib that gives the fabric excellent horizontal elasticity — crucial for a garment that needs to stretch comfortably around the body without the use of traditional shaping.
• Edge stitches: Each row begins and ends with a single knit edge stitch (K1), keeping the selvedges neat and making seaming during finishing much easier.

The recommended tension is 30 stitches × 32 rows = 10 × 10 cm
