Laett Jumper in BC Garn Baby Alpaca & Tussah Tweed – Pattern Summary

The Laett Jumper is a beautifully understated pullover sweater designed by Vithard Villumsen for BC Garn, pattern number 2393BC. This free downloadable PDF knitting pattern produces a lightweight, elegant jumper worked in the round, combining two of BC Garn's finest natural-fibre yarns for a sophisticated textural contrast. Rated as intermediate in difficulty, it is a rewarding project for knitters who are comfortable working in the round and managing two different yarns and needle sizes within a single garment.

What Is Being Made

The finished project is a classic pullover jumper worked seamlessly in the round on circular needles. It features a clean, relaxed silhouette with a ribbed cast-on edge and a smooth stockinette body. The design is available in three sizes:

• Small: 88 cm chest circumference, 50 cm length
• Medium: 96 cm chest circumference, 55 cm length
• Large: 104 cm chest circumference, 60 cm length

The length can also be adjusted to the knitter's desired measurement, making this a versatile and customisable pattern. The combination of Baby Alpaca and Tussah Tweed yarns gives the garment a refined, tactile quality — soft and fluid from the alpaca, with subtle rustic texture introduced by the tweed.

Materials Used

Yarn

This pattern calls for two specific BC Garn yarns, each playing a distinct role in the finished garment:

• BC Garn Baby Alpaca (colourway au118) — a 3-ply yarn used as the primary yarn for the body of the jumper. All sizes require 150g. Baby alpaca is prized for its exceptional softness, natural sheen, and lightweight warmth, making it ideal for a garment worn close to the skin.
• BC Garn Tussah Tweed (colourway tt07) — a 4-ply yarn used as a contrast or accent yarn. All sizes require 50g. Tussah silk tweed yarns typically incorporate slubby, textured fibres that add visual depth and a slightly earthy, artisan quality to the knitted fabric.

Needles

• 3.5 mm (US 4) circular needles in various lengths — used with the Tussah Tweed yarn
• 4.0 mm (US 6 / UK 8) circular needles in various lengths — used with the Baby Alpaca yarn

The use of two different needle sizes reflects the different gauges required to achieve the same stitch-per-centimetre ratio with each yarn, ensuring a consistent and balanced fabric throughout the garment.

Tension / Gauge

• Baby Alpaca on 4.0 mm needles: 23 stitches × 34 rows = 10 × 10 cm in stockinette stitch
• Tussah Tweed on 3.5 mm needles: 23 stitches × 34 rows = 10 × 10 cm in stockinette stitch

Achieving the correct gauge is especially important here, as the two yarns are deliberately matched to the same stitch and row count despite being worked on different needle sizes. Knitters are encouraged to swatch carefully before beginning.

Construction Method

The Laett Jumper is constructed in the round on circular needles, a technique that eliminates the need for seaming and produces a smooth, continuous fabric. The pattern begins by casting on with the Baby Alpaca yarn on the smaller 3.5 mm needles, then transitions to the larger 4.0 mm needles to work two ridges before continuing in stockinette stitch.
