Plymouth Yarn Aireado Vest Waistcoat Knitting Pattern

Plymouth Yarn Aireado Vest

Project Overview

The Plymouth Yarn Aireado Vest (Pattern No. 3285) is a classic waistcoat designed for knitters seeking a structured, versatile layering piece. This pattern is worked from the bottom up using the seamed, flat construction method, making it accessible for intermediate knitters. The vest features a tailored fit with finished measurements available in four sizes: 32", 36", 38", and 42" with minimal ease for a close-to-body silhouette. The finished length ranges from 21" to 23" depending on size, creating a traditional vest proportion suitable for various body types and style preferences.

Materials and Gauge

This project requires Plymouth Yarn Aireado yarn in color 22 Brown. Yardage needs are modest, requiring only 2 to 3 100-gram skeins depending on the finished size selected. The pattern is worked on US Size 9 (5.5 mm) needles to achieve a gauge of 20 stitches and 18 rows over 4 inches when worked in Twisted 1/1 Rib. Additional supplies include locking markers for collar attachment and a tapestry needle for finishing seams and weaving in ends.

Stitch Patterns and Techniques

The Aireado Vest employs two primary stitch patterns that work together to create visual interest and structural integrity. The 3/2 Rib Pattern forms the foundation of the garment body, worked over multiples of 5 plus 3 stitches. This pattern alternates knit 3 with purl 2 on the right side, creating a textured vertical line that provides subtle visual definition. The Twisted 1/1 Rib is used for the collar and ribbed edgings, worked over multiples of 2 plus 1 stitches. This rib features twisted knit stitches (knit through the back loop) paired with purls, creating a more refined, elastic edge that resists curling and provides excellent recovery.

Construction Method

The vest is constructed using a bottom-up, seamed approach worked flat on straight needles. This traditional method allows knitters to try on the piece as it progresses and make adjustments to length before binding off. The back piece is cast on first and worked in 3/2 Rib pattern to a length of 13 inches before armhole shaping begins. Armhole decreases are achieved through a combination of bind-offs at the edges and single decreases worked on right-side rows, creating a gradual slope that accommodates various fit preferences across the four size options.

Shaping and Fit Details

The pattern incorporates strategic shaping to create a fitted waistcoat silhouette. After establishing the 13-inch body length, armholes are shaped by binding off 4 stitches over 2 to 4 rows depending on size, followed by edge decreases worked every right-side row. The armhole depth ranges from 8 to 10 inches, providing comfortable movement while maintaining the structured aesthetic. Shoulder shaping uses stepped bind-offs to create a smooth cap, with final bind-off quantities varying from 6 to 10 stitches per shoulder depending on the selected size. The back neckline is left open for collar attachment, with approximately 31 to 36 stitches reserved for this opening.

Collar Construction

The collar is worked separately using the cable cast-on method, beginning with 45 stitches and worked entirely in Twisted 1/1 Rib. The collar length ranges from 53 to 55 inches depending on size, allowing it to wrap around the neckline with appropriate coverage. The pattern instructs knitters to use locking markers to position the collar with right sides facing, attaching it first to the left side of the back piece with the back's wrong side facing. The collar is then eased to fit the right side of the back and sewn into place along the seams and back neckline, creating a professional, finished appearance.

Finishing Techniques

The Aireado Vest employs seamed construction throughout, requiring careful seaming along the side edges and armholes to create clean, durable seams. The collar attachment uses both locking markers for positioning accuracy and hand-sewing for permanent attachment. The pattern recommends light steaming with no pressure if desired, which helps even out the rib texture and relax the finished garment without distorting the stitch definition. All ends are woven in using the tapestry needle, and the collar is bound off loosely in pattern to maintain elasticity at the neckline edge.

Yarn Characteristics

Plymouth Yarn Aireado is selected for this project to provide the appropriate drape, elasticity, and stitch definition required for a
