Pinstripe Sweater Jumper Knitting Pattern

Pinstripe Sweater in MODE at Rowan Alpaca Wool

What is Being Made

This is a children's raglan sweater designed by Quail Studio, available in five sizes ranging from 3–4 years through 11–12 years. The garment features a classic pinstripe pattern created through a carefully planned color-blocking stripe sequence. The sweater is knitted in the round from the bottom up, with raglan shaping at the armholes and a ribbed neckband finish. The design combines simplicity with visual interest, making it an ideal beginner-friendly project that introduces knitters to basic color work and garment construction.

Techniques Used

This sweater employs fundamental knitting techniques suitable for beginners. The main construction method involves knitting flat in pieces for the back, front, and sleeves, followed by raglan armhole shaping which creates the distinctive diagonal seam lines from underarm to neckline. The pattern uses stripe sequencing to build the pinstripe effect, with color changes worked at regular intervals throughout the piece. Mattress stitch is used to join the raglan seams, a technique that creates invisible, professional-looking seams. The neckband is worked in the round using circular needles, demonstrating basic circular knitting for a finished edge. Decreasing at each end of rows shapes the raglan armholes, and the pattern includes working decreases on alternating rows followed by consecutive rows to achieve the proper sleeve cap shaping.

Stitches Used

• Ribbing (K1, P1): The entire sweater is worked in a simple one-by-one rib pattern, which creates vertical lines and provides natural stretch and recovery. This rib is maintained throughout the body and sleeves until the raglan shaping begins.
• Knit and Purl stitches: The alternating knit and purl stitches form the foundation of the rib pattern used across the entire garment.
• Decreases: Single decreases at each end of rows shape the raglan armholes, worked on alternating rows and then on consecutive rows to taper the sleeve cap smoothly.
• Cast-on and cast-off: The pattern uses standard cast-on and cast-off methods to begin and finish the knitted pieces.

Stripe Sequence and Color Work

The pinstripe effect is achieved through a structured color-blocking approach rather than traditional striped knitting. The pattern specifies a repeating sequence of color changes: working 3 centimeters in yarn C, followed by 3 centimeters in yarn B, then returning to yarn C, and repeating this alternation. This creates balanced horizontal stripes that, when combined with the vertical lines of the rib stitch, produce the characteristic pinstripe visual effect. The color sequence is maintained as pattern correct throughout the raglan shaping, requiring knitters to continue the established stripe pattern while simultaneously decreasing stitches for the armhole.

Materials: Yarn and Needles

The sweater is knitted using Rowan Alpaca Wool yarn in a fingering or sport weight (50-gram balls). Three colors are required: Walnut (shade 016) for the main color, Olive (shade 018) for secondary stripes, and French (shade 013) for accent stripes. Yardage varies by size, with the largest size requiring 4 balls of Walnut, 2 balls of Olive, and 1 ball of French. The pattern calls for 3.75mm (US size 5) needles in two configurations: a standard pair of straight needles for working the flat pieces and a 40-centimeter circular needle for the neckband. The yarn choice of Alpaca Wool provides warmth, softness, and a subtle sheen, making it ideal for a children's garment that requires durability and comfort.

Sizing and Finished Measurements

The pattern provides five size options with actual chest measurements ranging from 61.5 centimeters (24¼ inches) for size 3–4 years to 84.5 centimeters (33¼ inches) for size 11–12 years. Each size includes proportionally adjusted stitch counts and row lengths, ensuring proper fit across the age range. The model shown in the pattern is size 9–10 years with a finished chest measurement of 78.5 centimeters (31 inches).

Tension and Gauge

The pattern specifies a tension of 26 stitches and 30 rows to 10 centimeters measured over the rib
