Groenlandia Jacket Crochet Pattern – Adriafil New Zealand and Decor Yarns

The Groenlandia Jacket is a striking, colorwork crochet jacket pattern from Adriafil, worked in a bold two-tone locked treble crochet design with decorative embroidered detailing. Available as a free downloadable PDF, this pattern is suitable for crocheters who are comfortable working with multiple yarn colors simultaneously and reading colorwork charts. The finished jacket features structured fronts, a shaped collar, set-in sleeves, and a distinctive zigzag embroidered finish created with a contrast yarn.

Garment Overview

The Groenlandia Jacket is a full jacket construction comprising four main pieces: a back, a right front, a left front, and two sleeves (right and left). Each piece is worked separately and then assembled. The design is sized for sizes 42, 44, and 46, making it suitable for a range of adult figures. The overall aesthetic is textured and richly colored, with the colorwork locked pattern giving the fabric a woven, intarsia-like appearance.

What Is Being Made

• Garment type: A structured crochet jacket with shaped armholes, a collar, and set-in sleeves
• Construction: Worked in separate flat pieces — back, right front, left front, right sleeve, and left sleeve — then seamed together
• Sizing: Three sizes available: 42, 44, and 46
• Collar shaping: The collar is formed by increasing one stitch every two rows, eight times, on the appropriate edge of each front piece
• Shoulder and armhole shaping: Armholes are shaped by binding off stitches in a stepped decrease sequence; shoulders are slanted to match across front and back pieces

Yarn and Materials

• Primary yarn: Adriafil New Zealand, an aran to super chunky weight yarn, used in two colorways:
  • Plum No. 37 — 300 g
  • Violet No. 48 — 300 g
• Total New Zealand yarn required: 600 g across both colors
• Accent yarn: Adriafil Decor in Violet No. 41 — several threads used for embroidered zigzag detailing on the finished jacket
• Crochet hook: No. 3.50 mm
• Additional tools: Tapestry needle for seaming and embroidery; bobbins recommended for managing multiple yarn colors during colorwork

Stitches and Techniques Used

• Chain stitch: Used to create the foundation chain for each piece
• Treble crochet: The primary stitch used throughout all pieces; each stitch is worked into the base chain or previous row following the colorwork chart
• Locked pattern (colorwork treble crochet): The signature technique of this jacket — treble crochet is worked following a chart using two separate yarn colors. One ball is used per color, with unused yarn threads braided along the back of the work and wound in when switching colors to work treble crochets in the alternate color. This creates a dense, interlocked colorwork fabric reminiscent of Fair Isle or intarsia techniques adapted for crochet.
• Bobbin technique: Bobbins are used to keep the two yarn colors organized and prevent tangling during the locked colorwork sections
• Embroidery (zigzag lines): After assembly, Adriafil Decor yarn in Violet No. 41 is used with a tapestry needle to embroider decorative zigzag lines onto the finished jacket surface, adding texture and visual interest
• Shaping techniques: Increases and decreases are worked at specified intervals to shape the sides of the jacket body, the sleeve taper, armhole openings, and the collar extension
