Mossy Triangle Hat by Kirsten McTeer

What is Being Made

The Mossy Triangle is a family-friendly knitted hat designed by Kirsten McTeer, available in five different sizes to accommodate wearers from baby through large adult. This downloadable PDF pattern provides complete instructions for creating a triangular-shaped hat with a modern, geometric aesthetic. The hat is suitable for year-round wear and works for the entire family, with sizes ranging from Baby (16"/40cm head circumference) through Large Adult (24"/64cm head circumference).

Sizing and Fit

The pattern includes five distinct size options:

• Baby: 16"/40cm head circumference
• Small Child: 18"/46cm head circumference
• Large Child: 20"/51cm head circumference
• Small Adult: 22"/56cm head circumference
• Large Adult: 24"/64cm head circumference

All sizes are designed with approximately 2"/5cm of negative ease, meaning the finished hat will be slightly smaller than the stated head circumference for a snug, secure fit. Kirsten McTeer recommends checking your personal tension before beginning to ensure correct sizing and accurate yarn yardage calculations for your chosen size.

Knitting Techniques Used

This beginner-level pattern uses knitting in the round as the primary construction method, which creates a seamless, tubular fabric ideal for hat construction. The pattern employs stocking stitch as the main stitch pattern, which creates the classic smooth, V-textured fabric that forms the foundation of the hat's structure. The triangular shaping is achieved through strategic increases and decreases worked throughout the pattern rows.

Stitches and Stitch Patterns

The Mossy Triangle utilizes stocking stitch (knit stitches on the right side, purl stitches on the wrong side when working flat, or continuous knit stitches when working in the round) as the primary fabric. The pattern is worked to a specific tension of 23 stitches and 32 rows over 4"/10cm of stocking stitch, which is essential for achieving the correct finished dimensions. The geometric triangle shaping is created through increases and decreases integrated into the stocking stitch fabric, allowing the hat to develop its distinctive silhouette.

Materials and Yarn Requirements

The Mossy Triangle pattern calls for DK weight yarn, with yardage varying by size:

• Baby: 84 yards (77 meters)
• Small Child: 105 yards (96 meters)
• Large Child: 130 yards (119 meters)
• Small Adult: 155 yards (142 meters)
• Large Adult: 190 yards (174 meters)

DK (double knitting) weight yarn is a versatile, medium-weight yarn that produces a fabric with good drape and structure, making it ideal for fitted hat designs. The pattern requires two sets of 3.5mm (US4) and 3.75mm (US5) circular knitting needles for knitting in the round. The smaller needles (3.5mm/US4) are used for the ribbed cuff or edge sections, while the larger needles (3.75mm/US5) are used for the main body to achieve the specified pattern tension. Additional materials include three stitch markers (two matching and one different to mark the beginning of the round) and a darning needle for weaving in yarn ends after completion.

Pattern Format and Instructions

This is a downloadable PDF pattern provided by independent designer Kirsten McTeer. Instructions are written for the Baby size, with figures for all larger sizes provided in parentheses throughout the pattern. When only a single figure appears without parenthetical alternatives, that instruction applies uniformly across all five sizes. This format allows knitters to easily locate their size while following a single set of instructions.
