Blooming Bomber Jacket - Free Crochet Pattern For Women in Paintbox Yarns Simply Aran

Blooming Bomber Jacket – Free Crochet Pattern for Women by Katie Jones in Paintbox Yarns Simply Aran

About This Pattern

The Blooming Bomber Jacket is a vibrant, colour-blocked crochet pattern designed by Katie Jones and made using Paintbox Yarns Simply Aran. This free, downloadable PDF pattern is rated intermediate in difficulty and is aimed at women who are comfortable with basic crochet construction and are ready to take on a fully shaped garment with multiple colours. The finished jacket has a bold, graphic aesthetic, combining a deep Pure Black base with a rainbow of accent shades that give the piece its signature blooming, floral-inspired character.

What Is Being Made

This pattern produces a women's bomber-style crochet jacket, available in two sizes: S/M and M/L. The finished chest measurements are 62 cm (24½ in) for S/M and 66 cm (26 in) for M/L. The bomber silhouette is a classic, relaxed shape with a structured body, making it a wearable statement piece suitable for layering over casual outfits. The colourful detailing gives it a contemporary, artisan feel that stands out from more traditional crochet garments.

Techniques Used

• Worked in the round – Key sections of the jacket, including the body panels, are constructed using circular crochet techniques, which create seamless, continuous fabric and reduce the need for extensive finishing and seaming.
• Stripes – The pattern makes extensive use of stripe sequences, alternating between Pure Black (A) and the various accent colours to build up the bold, multi-coloured design. Stripe work in crochet involves changing yarn at the end of rows or rounds to introduce new shades cleanly.
• Cluster stitches – The pattern calls for cluster stitches, which involve working multiple incomplete stitches into the same or adjacent positions and joining them at the top, creating a gathered, textured effect that adds visual interest and dimension to the fabric.
• Colour changes – Working with up to nine different yarn colours requires careful management of yarn ends and clean colour transitions, a key intermediate skill this pattern helps develop.

Stitches Used

• Treble crochet (tr) / Double crochet (US) – The primary stitch used throughout the body of the jacket, forming the main fabric. The pattern is measured over a tension swatch that includes four rows of treble crochet.
• Half treble crochet (htr) / Half double crochet (US hdc) – Used in alternating rows within the stitch pattern sequence, the half treble sits between a double and a full treble in height, contributing to the textural rhythm of the fabric.
• Double crochet (dc) / Single crochet (US sc) – Incorporated into the row repeat, the double crochet is the shortest of the main stitches used and helps create variation in the fabric's surface texture.
• Double treble (dtr) / Treble (US tr) – A taller stitch used for specific design elements, the double treble adds height and drama where required in the pattern.
• Slip stitch (ss) – Used for joining rounds and finishing edges neatly.
• Chain (ch) – Used for foundation chains, turning chains, and creating spaces within the fabric.
• Cluster (cl) – A combination stitch that groups multiple loops together, adding texture and decorative detail to the design.

Tension and Gauge

The pattern specifies a tension of 13 stitches and 7 rows to 10 cm / 4 in, measured over the stitch pattern sequence of 4 treble rows, 2 half treble rows, and 1 double crochet row. Achieving correct tension is especially important in a garment like this bomber jacket, where fit and finished measurements depend on accurate stitch sizing. Crocheters are encouraged to work a tension swatch before beginning and adjust their hook size if necessary.
