Rainbow Jacket - Block Party

Rainbow Jacket – Block Party by Caroline Murphy

What Is Being Made

The Rainbow Jacket – Block Party is a colorful crochet jacket designed by Caroline Murphy (caroline30 on Ravelry). This garment is constructed using a modular block method, where individual crocheted squares are joined together to create the finished jacket. The design is suitable for chest sizes 81–101.5cm (32–40 inches), with actual finished measurements of 128cm (50.25 inches) across the bust and 68cm (26.75 inches) in length from shoulder to hem. The sleeves measure 45.5cm (18 inches) from underarm to cuff. The jacket's "Block Party" name reflects its construction technique, which relies on assembling multiple individual squares into a cohesive garment.

Techniques Used

This crochet jacket employs the popular modular or block construction method, where the garment is built from individual crocheted squares that are later joined together. This technique offers several advantages for crocheters: it breaks down a large project into manageable, portable pieces, allows for easy color changes and creative color placement, and provides natural stopping points throughout the project. The pattern uses American crochet terminology throughout. Edging work is incorporated using a smaller hook size, which creates a refined finish around the perimeter of the completed jacket. The use of two different hook sizes—a 4mm hook for the main squares and a 3mm hook for edgings—demonstrates how hook size variation can achieve different fabric densities and create polished finishing details.

Stitches Used

The Rainbow Jacket – Block Party utilizes fundamental crochet stitches that make it accessible to beginner-level crocheters. The primary stitches employed include:

• Chain (ch): The foundation stitch used to begin rounds and create chain spaces
• Double crochet (dc): The main stitch used to build the body of each square block
• Single crochet (sc): Used for edging and finishing details
• Slip stitch (ss): Used to join rounds and create seamless transitions between rows
• Chain space (ch-sp): The gaps created by chain stitches, which form an important structural element of the square blocks
• Decrease (dec): Used where shaping is required

Each individual square block measures 16cm (6.25 inches) and is worked in the round using these stitches. The pattern demonstrates how simple stitches, when combined in a structured sequence, create attractive geometric blocks that can be arranged in a rainbow color progression.

Materials and Yarn Requirements

The Rainbow Jacket – Block Party requires approximately 1,430 metres (1,564 yards) of DK weight yarn in total. DK yarn is a medium-light yarn weight that works well for garments requiring drape and flexibility. The pattern calls for assorted colours, making this an ideal project for using yarn stash in multiple colors or for purchasing a rainbow color palette to create the jacket's vibrant appearance. A 4mm crochet hook is used for the main square blocks, with a tension of 16 stitches and 7 rows equaling 10cm (4 inches). A 3mm crochet hook is used for the edging work, creating a tighter, more refined finish. Achieving the correct tension is important for ensuring the finished jacket meets the specified measurements and fits properly.

Difficulty Level

This pattern is rated as beginner-friendly, making it an excellent choice for crocheters new to garment construction or modular techniques. The use of basic stitches, the repetitive nature of the block construction, and the clear written instructions using standard American crochet abbreviations support accessibility for newer crafters. The modular approach also means that beginners can work at their own pace, completing one square at a time before moving on to the next.
