Geometric Intarsia Sweater in BC Garn Semilla Fino & Kid Mohair – Pattern 2321BC by Charlotte Kaae

This free downloadable PDF knitting pattern, numbered 2321BC and designed by Charlotte Kaae for BC Garn, guides knitters through the construction of a relaxed, oversized geometric intarsia sweater. The design combines bold colour-block geometry with a beautifully soft, lightweight fabric, making it a striking yet wearable wardrobe piece. The pattern is rated intermediate in difficulty, making it ideal for knitters who are comfortable with basic shaping and are ready to explore the rewarding technique of intarsia colourwork.

What Is Being Made

The finished project is a pullover sweater featuring geometric intarsia colourwork panels worked across the body and sleeves. It is available in four sizes — S, M, L, and XL — with a generously wide silhouette. Key finished measurements are as follows:

• Width: 120 (128) 136 (144) cm
• Full length: 80 (80) 82 (82) cm
• Sleeve length: 56 (56) 58 (58) cm

The wide, relaxed proportions give the sweater a contemporary, fashion-forward feel, and the geometric colour blocks create a bold visual statement that works beautifully in the muted, natural tones characteristic of BC Garn Semilla Fino.

Techniques Used

Intarsia is the central technique of this pattern. Unlike stranded colourwork, intarsia involves working separate, individual sections of colour using their own yarn supply — each colour block is worked with its own length or ball of yarn, and the yarns are twisted together at colour joins to prevent holes. This method is particularly well suited to large geometric shapes and clean, straight-edged colour transitions, which is exactly what this design calls for. Knitters new to intarsia will find that the geometric nature of the shapes — with their straight lines and defined angles — makes this an approachable introduction to the technique.

Additional techniques referenced in the pattern include:

• Shaping with decreases: K2tog (knit two together) and SSK (slip, slip, knit) are used for paired, mirrored decreases, commonly applied at sleeve and neckline shaping
• Increases: The Inc method — lifting the loop between two stitches with the left needle and knitting into the back of the loop — is used for sleeve shaping
• Selvedge stitches: The first and last stitch of rows are worked as selvedge stitches to create neat, seam-friendly edges
• Seaming: As a constructed sweater with separate pieces, seaming is required to join the body and sleeves

Stitches Used

• Stockinette stitch (St st) — the primary stitch throughout the garment, worked by knitting on the right side and purling on the wrong side, creating the smooth, flat fabric that best showcases the intarsia colour blocks
• Knit (K) and Purl (P) — fundamental stitches used throughout construction and any ribbed or textured edging sections

Yarn and Materials

The sweater is worked with a held double strand — one strand of BC Garn Semilla Fino (a 4-ply weight yarn) held together with one strand of BC Garn Super Kid Mohair (a lace weight yarn). This combination creates a fabric that is both substantial and incredibly soft, with the mohair adding a delicate halo and warmth to the natural fibres of the Semilla Fino.

Three colourways of Semilla Fino are used to create the geometric colour blocks:

• Shade ox104 — 3 (3) 4 (4) balls
• Shade ox107 — 3 (3) 4 (4) balls
