Treasach Crochet Jacket by Caroline Murphy

What Is Being Made

Treasach is a downloadable crochet jacket pattern designed by independent designer Caroline Murphy. This intermediate-level garment is constructed using a modular square-based technique, creating a vibrant, patchwork-style jacket. The finished jacket measures 114.25cm (45 inches) around the bust with a length of 48.25cm (19 inches) from shoulder to hem, and sleeves that extend 58.25cm (23 inches) from the underarm.

Construction Technique

The Treasach jacket is built using a modular square construction method, where individual crochet squares are created separately and then joined together to form the complete garment. This technique allows for flexibility in color placement and makes the project manageable in sections. The pattern begins with creating a foundational square worked in rounds from the center outward, with subsequent rounds expanding the square and introducing color changes.

The modular approach means each square is worked independently before being assembled, making this an excellent project for crafters who enjoy building garments piece by piece. The use of assorted colors throughout the yarn creates a dynamic, multi-colored finished piece.

Crochet Stitches Used

The Treasach pattern employs fundamental crochet stitches suitable for intermediate-level crafters:

• Chain stitch (ch): Used to create the foundation and spacing between stitch groups
• Double crochet (dc): The primary stitch forming the body of each square, worked in groups to create texture and structure
• Single crochet (sc): Utilized for finishing and edging details
• Slip stitch (ss): Used to join rounds and create seamless transitions between sections
• Chain spaces (ch-sp): Gaps created by chain stitches that form corner details and decorative elements in the square pattern

Materials and Tools

The Treasach jacket requires approximately 1,275 metres (1,395 yards) of DK weight yarn in assorted colors, allowing crafters to use stash yarn or coordinate multiple complementary shades for a cohesive design.

Two crochet hook sizes are needed for this project:

• 5mm crochet hook: Used for the main fabric construction, worked to a gauge of 16 stitches and 7 rows over 10cm (4 inches)
• 4mm crochet hook: Used for finishing edgings to create a neat, refined border around the completed jacket

The pattern is written using American crochet terminology, making it accessible to crocheters familiar with US stitch abbreviations and conventions.

Difficulty Level

Rated as intermediate difficulty, the Treasach jacket is suitable for crocheters with foundational skills who are ready to tackle garment construction. The modular square technique breaks the project into manageable components, while the use of basic stitches keeps the learning curve moderate. Crafters should be comfortable reading pattern abbreviations, maintaining consistent tension, and joining pieces together.
