Noro Tyto Jumper Knitting Pattern

Noro Tyto Sweater

What is Being Made

The Noro Tyto is an intermediate-level knitted sweater designed in five sizes: Small, Medium, Large, 1X, and 2X. This garment features finished bust measurements ranging from 40½ inches (103 cm) in the smallest size to 49 inches (124 cm) in the largest size, with a length that varies from 22 inches (56 cm) to 24 inches (61 cm) depending on the selected size. The upper arm width ranges from 15½ inches (39.5 cm) to 19¼ inches (49 cm), providing a comfortable fit across multiple body types.

Construction Techniques

The Noro Tyto sweater is constructed using a bottom-up, seamed, and worked-flat approach. This traditional method means the sweater pieces are knitted individually in flat panels from the lower edge upward, then assembled together using seaming techniques. The bottom-up construction allows for easy fitting adjustments during the knitting process and provides clear finishing points for seaming the body and sleeve pieces together.

The pattern incorporates several specialized knitting techniques to create texture and structure. Fisherman's Rib is the primary stitch pattern used throughout the sweater, which is worked over an even number of stitches. This technique involves knitting one stitch in the row below (abbreviated as K1B) in alternation with purl stitches, creating a dense, textured fabric with excellent elasticity and warmth. The pattern includes instructions for working "no stitch" areas on charts, where shaded spaces indicate stitches that have been decreased or not yet made—in these cases, knitters skip over the marked spaces and work only the active stitches.

Additional techniques featured in the pattern include slip, slip, knit/purl decreases for shaping, yarn overs for creating new stitches, selvage stitches along edges to facilitate easier seaming, and pick up and knit/purl methods for adding stitches along finished edges. Stitch markers are used throughout to help track pattern repeats and shaping points.

Stitches Used

• Fisherman's Rib: The primary stitch pattern, worked with purl stitches alternating with knit stitches worked into the row below (K1B), creating a textured, elastic fabric
• Knit and Purl stitches: Foundation stitches used throughout the pattern
• Slip, Slip, Knit/Purl (SSK/SSP): Decrease stitches created by slipping two stitches knitwise or purlwise individually, then inserting the left needle through their fronts and knitting or purling them together
• Yarn Overs: Used to create new stitches and add texture
• Slip Stitches: Stitches passed from the left needle to the right needle without being worked, used for selvage edges and pattern transitions

Materials

The Noro Tyto sweater is designed to be knitted with Noro Okunoshima yarn in colorway #09. The yardage requirements vary by size: Small and Medium sizes require 5 balls of 100g each, while Large and 1X sizes need 6 balls, and the 2X size requires 7 balls. This yarn choice contributes to the sweater's distinctive appearance and drape.

The pattern calls for two pairs of needles in different sizes to manage gauge and create proper fabric density. The smaller pair is US 7/4.5mm needles, used for ribbing or edging sections, while the main body is worked on US 8/5mm needles or the size required to achieve proper gauge. The recommended gauge for this sweater is 15 stitches and 30 rows to 4 inches (10 cm) over Fisherman's Rib using the US 8/5mm needles. Achieving this gauge is essential for proper fit, and knitters are advised to take time to check their gauge before beginning the project.
