Diamond Jumper in BC Garn Semilla – Pattern Summary (Design No. 2386BC by Sanne Fjalland)

What Is Being Made

This is a free, downloadable PDF knitting pattern for the Diamond Jumper, an elegant pullover sweater designed by Sanne Fjalland and published by BC Garn (pattern number 2386BC). The jumper is a classic, flattering design distinguished by a repeating lace diamond motif scattered across both the front and back pieces, giving it a delicate, textured appearance against a smooth stockinette background. It is available in four sizes — S, M, L, and XL — with chest measurements ranging from 92 cm to 109 cm and lengths from 60 cm to 63 cm, making it suitable for a wide range of adult knitters.

Yarn and Materials

The pattern is written specifically for BC Garn Semilla, a DK weight yarn, in colourway ob101. The yardage required varies by size:

• S and M: 450 g of BC Garn Semilla
• L: 500 g of BC Garn Semilla
• XL: 550 g of BC Garn Semilla

BC Garn Semilla is a natural, eco-conscious yarn, and its smooth DK weight is well suited to showcasing both the clean stockinette fabric and the intricate lace diamond details throughout the garment.

Needles Required

Three needle sizes are used in this pattern, reflecting the need for different gauges across the garment's construction:

• 3 mm circular needle (40 cm) — US size 3 / UK size 10
• 3.5 mm needles and 3.5 mm circular needle (40 cm) — US size 5 / UK size 9
• 4 mm needles — US size 6 / UK size 8

Tension / Gauge

The recommended tension is 22 stitches and 33 rows to 10 x 10 cm in stockinette stitch. Achieving the correct gauge is important for ensuring the finished garment matches the stated chest and length measurements.

Techniques and Construction

The Diamond Jumper is rated as an intermediate level knitting project, making it ideal for knitters who are comfortable with basic shaping and are ready to introduce lace patterning into their work. The body pieces — both front and back — are worked flat in rows, with a selvedge stitch (knit on every row) at each end to create a neat edge for seaming.

The main fabric is stockinette stitch (knit on the right side, purl on the wrong side), which provides a smooth, classic background. Scattered across this fabric are lace diamond motifs, worked following a dedicated chart included in the pattern. These diamonds are placed at specific intervals as the work grows in length, creating a staggered, all-over diamond arrangement rather than a continuous lace panel.

The placement of the lace diamonds is carefully sequenced by measurement:

• At 5 cm of work, two diamonds are introduced simultaneously, one on each side of the piece, each spanning 21 stitches.
• At 17 cm, a single central diamond is worked.
• At 29 cm, another single diamond is placed.
• At 41 cm, a further single diamond is added.

This staggered placement creates the impression of diamonds floating freely across the fabric, a hallmark of Sanne Fjalland's elegant, understated aesthetic.

Stitches Used

• Stockinette stitch (St st) — knit on right side, purl on wrong side; forms the main body fabric
• Reverse stockinette stitch (Rev St st) — purl
