Tullia Crochet Jacket by Caroline Murphy

What is Being Made

Tullia is a downloadable crochet jacket pattern designed by Caroline Murphy. This intermediate-level garment features a finished bust measurement of 122cm (48 inches) with a length from shoulder of 66cm (26 inches) and sleeve length from underarm of 50.75cm (20 inches). The jacket is constructed using a modular granny square technique, making it an ideal project for crocheters looking to build garment construction skills through a structured, block-based approach.

Techniques Used

The Tullia jacket employs the classic granny square method as its primary construction technique. This modular approach involves creating individual squares that are subsequently joined together to form the body and sleeves of the jacket. The use of contrasting yarn colors in successive rounds of each square creates visual interest and dimension. The pattern utilizes both a 5mm crochet hook for the main fabric and a 4mm crochet hook for finishing edgings, allowing for refined edges and a polished final appearance. The gauge-conscious construction—requiring 16 stitches and 7 rows over 10cm (4 inches) in granny stitch—ensures proper fit and drape.

Stitches Used

The pattern is written using American crochet terminology and incorporates the following stitches:

• Chain (ch): The foundation stitch used to begin rounds and create chain spaces
• Double crochet (dc): The primary stitch forming the body of the granny squares
• Single crochet (sc): Used for joining and finishing techniques
• Slip stitch (ss): Employed to join rounds and close circles
• Chain space (ch-sp): The openwork gaps created between groups of stitches, particularly the characteristic 2-chain spaces at the corners of granny squares

Materials and Yarn

The Tullia jacket requires approximately 1,525 metres (1,668 yards) of DK weight yarn in assorted colors. The use of multiple colors is integral to the design, as each granny square round is worked in contrasting yarn to create the characteristic striped effect of this construction method. The pattern calls for a 5mm crochet hook to achieve the specified gauge of 16 stitches and 7 rows equaling 10cm (4 inches) over granny stitch, with a 4mm hook reserved for working edgings. The DK yarn weight provides a balanced fabric suitable for a wearable jacket with good drape and structure.
