Optical In Rowan Kaffe Fassett Felted Tweed Knitting Pattern

Kaffe Fassett Optical Vest in Rowan Felted Tweed

What Is Being Made

This is a knitted vest pattern from the Kaffe Fassett collection, designed to fit chest measurements ranging from 71–77 cm (28–30 inches) up to 152–157 cm (60–62 inches). The garment features an optical patterned design created through colorwork knitting techniques, combining multiple yarn colors for visual interest and depth.

Craft and Technique Overview

The Optical vest is a knitting project suitable for knitters with intermediate skill level. The pattern requires working with multiple yarn colors simultaneously to create the optical effect across the body and armholes. Shaping techniques include strategic decreases at the neck edge, shoulder shaping through cast-offs, and careful stitch management to maintain pattern continuity throughout construction.

Stitches and Pattern Work

The vest is worked primarily in stockinette stitch (abbreviated as st st in the pattern), which provides a smooth, classic fabric base. The optical pattern is achieved through patterned stockinette stitch using color changes. Construction involves working separate pieces—back and front panels—with shaping accomplished through:

• Decreasing 1 stitch at neck edges on alternating rows for gradual neckline shaping
• Casting off groups of stitches at the beginning of rows to create shoulder seams
• Maintaining pattern alignment while executing all shaping decreases
• Creating a neckband using a circular needle to pick up and finish the neck opening

Materials and Needle Specifications

This pattern uses Rowan Felted Tweed yarn in three colorways:

• Fuchsia (K0011) – Color A
• Daffodil (K0012) – Color B
• Marigold (K0013) – Color C

Rowan Felted Tweed is a 50-gram skein yarn. The pattern requires varying quantities of each color depending on the chosen size, ranging from 2 skeins to 4 skeins per color for larger sizes.

Needles and Gauge

The pattern calls for two needle sizes to create proper fabric structure:

• 3¼mm (US 3) needles – used for ribbed sections and initial cast-on
• 4mm (US 6) needles – used for the main patterned stockinette stitch sections
• 3¼mm (US 3) circular needle – no more than 40 cm long – used for the neckband finish

Tension (Gauge): 22 stitches and 30 rows measured over 10 centimeters using 4mm (US 6) needles in patterned stockinette stitch. Achieving correct gauge is essential for proper fit across all size options.

Pattern Structure

The vest is constructed in separate pieces with the following sections:

• Back panel: Cast on using 3¼mm needles and yarn A, then switched to 4mm needles for patterned work. Includes armhole shaping and shoulder decreases.
• Front panel: Worked similarly to the back until the front neck division. The front features a deeper neckline created by dividing stitches and working each shoulder separately with progressive neck edge decreases.
• Neckband: Worked in the round using the circular needle, picking up stitches from the neck opening and incorporating the held center front stitches.

Size Range and Customization

The pattern provides nine size options with corresponding stitch counts and yardage requirements. Each size includes specific shaping instructions, allowing knitters to customize the optical vest to their exact measurements. The detailed sizing chart ensures proper fit from extra-small through extra-large dimensions.
