Bulky Thrummed Mittens

Bulky Thrummed Mittens by Stephanie Lau

Project Overview

These crochet mittens feature a traditional thrummed construction, a specialized technique that creates an exceptionally warm wool lining perfect for cold weather. The design combines chunky yarn with wisps of unspun wool roving to produce mittens with built-in insulation and a distinctive puffy aesthetic. Available in both adult and child sizes, these mittens work up quickly due to the bulky yarn weight, making them an ideal project for crafters seeking fast results without sacrificing warmth or style.

What Is Being Made

Bulky crochet mittens designed by Stephanie Lau that showcase the traditional thrummed mitten technique. The finished mittens feature puffy heart details and are available in two sizes: adult mittens measuring 10.5 inches (27 cm) long by 9.5 inches (24 cm) wide, and child mittens measuring 8 inches (20 cm) long by 8 inches (20 cm) wide. These mittens are constructed with a wool-lined interior created through the thrumming process, offering exceptional warmth and durability.

Crochet Techniques Used

The primary technique featured in this pattern is thrumming, a traditional method originating from Newfoundland and Labrador. This specialized technique involves crocheting wisps of unspun wool roving, called thrums, directly into the fabric as you work. The thrums are incorporated throughout the mitten construction to create a dense wool lining that provides superior insulation. Single crochet stitches form the foundation of the mitten structure, worked in continuous rounds to create a seamless, fitted garment. The pattern includes construction of puffy heart embellishments that add visual interest to the finished mittens.

Stitches and Stitch Details

• Single crochet (sc) – The primary stitch used throughout the mitten construction, worked in continuous rounds
• Thrummed single crochet – Single crochet stitches worked with wool roving thrums incorporated into each stitch for insulation
• Puffy heart details – Decorative elements added to enhance the visual appeal of the finished mittens

Materials and Yarn Specifications

The pattern calls for 120 grams (132 yards) of bulky level 5 yarn, with a recommended gauge of 10 stitches and 12 rounds equaling 4 inches in single crochet. A 5 mm crochet hook is used to work with the bulky yarn weight. The designer used Hue + Me in "Desert" by Lion Brand Yarn for the main mitten fabric. Additionally, 60 grams of wool roving is required to create the thrums that form the insulating lining. The pattern specifically recommends "Fifty Fifty Yarn" from the Lion Brand Collection, a super bulky yarn composed of 50% alpaca and 50% wool, which provides both warmth and durability.

Difficulty Level

This pattern is rated as intermediate difficulty. While the basic stitches are straightforward single crochet, the thrumming technique requires practice and familiarity with incorporating wool roving into crochet stitches. Crafters should have foundational crochet skills before attempting this project, as the thrumming process adds complexity beyond basic stitch work. The pattern includes references to a step-by-step blog post to supplement the written instructions and provide additional guidance on the thrumming technique.
