Trinity Stitch Hat

Trinity Stitch Hat by Sarah Ruane

What is Being Made

The Trinity Stitch Hat is a structured crochet hat designed by Sarah Ruane and available in four size options: Toddler, Child, Adult Small (S), and Adult Medium (M). This downloadable PDF pattern creates a finished hat with a ribbed cuff and textured body, offering versatile sizing for the entire family. The hat combines functional ribbing at the base with an eye-catching stitch pattern throughout the main crown.

Finished Measurements

• Toddler: 16" head circumference (including ribbing), 18" circumference without ribbing, 7" height
• Child: 18" head circumference (including ribbing), 20" circumference without ribbing, 7.75" height
• Adult Small (S): 20" head circumference (including ribbing), 22" circumference without ribbing, 8.75" height
• Adult Medium (M): 22" head circumference (including ribbing), 25" circumference without ribbing, 8.75" height

Stitches and Techniques Used

This pattern features the trinity stitch as the primary textured element in the hat body, creating visual interest and dimension. The ribbing section utilizes half double crochet (hdc) combined with slip stitch to form a stretchy, fitted cuff that sits comfortably on the head. The combination of these stitches provides both elasticity and structure, ensuring the hat maintains its shape while accommodating different head sizes.

Hook and Yarn Requirements

The Trinity Stitch Hat is worked with two different hook sizes to achieve proper gauge and construction. The ribbing section uses a 5.5mm (I-9) hook, while the main body is worked with a 6.5mm (K-10.5) hook or the size required to meet the specified gauge. This hook size variation is intentional, allowing the ribbing to be slightly tighter for a secure fit while the larger hook creates the appropriate drape and texture in the body.

The pattern calls for #5/Bulky weight yarn, classified as chunky yarn. The yardage requirements vary by size: Toddler requires approximately 95 yards total (60 yards in the primary color and 35 yards in the contrast color), Child requires approximately 115 yards total (70 yards primary and 45 yards contrast), with larger sizes requiring proportionally more yardage. The pattern was designed using Paintbox Yarns Simply Chunky, a 100% acrylic yarn with a yardage of 149 yards per 100g skein, though any #5/Bulky weight yarn of similar weight and yardage per gram can be substituted.

Gauge

Achieving proper gauge is essential for this pattern. The ribbing gauge is 6 stitches by 13 rows equaling 1.75" by 4" (4cm by 10cm) when measured over the hdc and slip stitch ribbing pattern. The body gauge is 12 stitches by 11 rows equaling 4" by 4" (10cm by 10cm) when measured over the trinity stitch pattern. Checking gauge before beginning ensures the finished hat will fit correctly across all four sizes.

Difficulty Level

Rated as intermediate, this pattern assumes familiarity with basic crochet techniques including chain stitches, half double crochet, slip stitches, and the ability to read pattern instructions. The trinity stitch, while visually striking, requires attention to stitch placement and consistency, making this project suitable for crocheters who have completed several basic projects and are ready to expand their stitch repertoire.
