Running Rings Jar Cosy

Running Rings Around Granny Jar Cosy

What is Being Made

The Running Rings Around Granny Jar Cosy is a decorative crochet cover designed to fit over jam jars and similar containers. This pattern creates a functional yet decorative piece perfect for outdoor living spaces, particularly when used to diffuse bright lighting sources like fairy lights or string lights. The jar cosy allows light to glow softly through the crocheted fabric while adding a handmade, cosy aesthetic to re-used glass jars. Two complete jar covers can be made from the specified yardage provided in the pattern.

Crochet Techniques and Construction

This beginner-level crochet pattern utilizes fundamental crochet techniques accessible to those new to the craft. The design features a granny-style construction, which is a classic crochet approach that builds fabric through repeating motifs and rounds. The pattern works in the round, building the jar cosy from the bottom up or in a circular construction method typical of granny square variations. The use of multiple yarn colors creates the visual "running rings" effect that gives the pattern its distinctive name, with color changes worked throughout the rounds to build the striped or ringed appearance.

Stitches Used

• Chain (Ch): The foundation stitch used to create the base loops and turning chains throughout the pattern
• Slip Stitch (Sl St): Used to join rounds and create seamless transitions between color changes and pattern sections
• Half Treble Crochet (HTr): A medium-height stitch that creates a balanced, open fabric suitable for light diffusion
• Half Treble Crochet 2 Together (HTr2Tog): A decrease stitch used to shape the jar cosy and adjust stitch counts as needed for proper fit
• Treble Crochet (Tr): A taller stitch that adds height and texture variation to the pattern

Materials and Yarn Specifications

The Running Rings Around Granny Jar Cosy is worked in DK weight yarn, a lightweight yarn that creates a delicate, open fabric ideal for diffusing light. The pattern requires 10 grams (50 meters) each in 4 different color shades, with a total of 40 grams of yarn needed to complete two jar covers. The designer used Woman's Institute Premium Acrylic Yarn (100g/250m per ball) in the following four colors:

• Colour 1: Plum
• Colour 2: Fuchsia
• Colour 3: Baby Pink
• Colour 4: White

The pattern is worked with a 4mm crochet hook (Size G-6), which is the standard hook size for DK weight yarn and creates an appropriately sized fabric with good drape and light-diffusing properties.
