Tux, the Linux Penguin

Tux, the Linux Penguin Amigurumi Crochet Toy

What Is Being Made

Tux, the Linux Penguin is a 6-inch tall crocheted amigurumi toy designed by Stacey Trock. This stuffed animal character represents the Linux penguin mascot, with an official date of birth in October 2008. The finished toy is a soft, huggable plush suitable for display or play, created entirely through crochet techniques.

Crochet Techniques and Construction Methods

This intermediate-level crochet project uses several fundamental amigurumi construction techniques to build a three-dimensional toy. The pattern emphasizes stitching into the back loop of stitches, which creates distinctive ridges on the right side of the finished pieces. This textural detail adds visual interest and definition to the penguin's body segments. The toy is constructed in the round, meaning stitches are worked continuously in circular rows rather than in flat panels, allowing for seamless, tubular sections that form the penguin's body, head, and limbs.

The back-loop-only stitch technique is a signature feature of this design. By consistently working into only the back loop of each stitch (rather than under both loops), the crocheter creates raised ridges that enhance the toy's appearance and give it a more polished, professional finish. This method requires attention to detail but is achievable for intermediate crafters.

Stitches Used

• Chain (ch): The foundation stitch used to create loops and starting chains for various sections
• Single crochet (sc): The primary stitch throughout most of the pattern, worked into the back loop to create textured ridges
• Double crochet (dc): Used for sections requiring taller stitches and faster fabric growth
• Single crochet 2 together (sc2tog): A decrease stitch used to shape the toy and reduce stitch counts as sections taper

Materials and Yarn Specifications

This pattern calls for worsted weight yarn in three colors: black (MC—main color), white (SC—secondary color), and yellow (AC—accent color). The sample was created using Ella Rae Classic 100% wool worsted weight yarn in specific colors (Black #32, White #01, and Yellow #44), though the pattern notes that any worsted weight yarn works equally well, including acrylic options such as Red Heart.

Additional materials required include a Size H crochet hook, a tapestry needle for weaving in yarn ends and assembly, two 12mm black animal eyes for facial features, and fiberfill stuffing to fill the completed toy and give it dimension and weight. The combination of these materials creates a durable, cuddly finished toy.

Skill Level and Suitability

Rated as an intermediate project, Tux requires familiarity with basic crochet stitches and comfort working in the round. The emphasis on back-loop stitching and the need to maintain consistent tension throughout adds a moderate challenge, making this pattern ideal for crocheters who have completed several beginner projects and are ready to develop more advanced shaping and finishing skills.
