Iago Waistcoat

Iago Waistcoat by Kari-Helene Rane

Overview

The Iago Waistcoat is a knitted sleeveless garment designed by Kari-Helene Rane, available in five sizes ranging from XS to XL to fit bust measurements of 73 to 112 centimeters (29 to 44 inches). This intermediate-level knitting project combines multiple stitch techniques and construction methods to create a structured, layering piece suitable for various occasions.

What Is Being Made

This is a classic waistcoat—a sleeveless, button-front vest garment constructed from separate knitted pieces that are assembled together. The design features distinct sections with contrasting stitch patterns that create visual interest and textural variation across the front and back panels.

Construction and Pieces

• Front panel: Knitted as a single piece using two strands of yarn held together
• Back panel: Knitted as a single piece using a single strand of yarn
• Pieces are worked flat and then assembled

Knitting Techniques Used

The Iago Waistcoat employs several fundamental knitting techniques to achieve its finished structure. The garment utilizes both garter stitch and seed stitch as primary stitch patterns, creating distinct textural zones. Garter stitch—formed by knitting every row—produces a dense, ridged fabric with excellent drape and stability. Seed stitch, created by alternating knit and purl stitches in a checkerboard pattern, adds a refined, bumpy texture. The pattern requires careful attention to tension and row counting to ensure proper fit and proportion across the five size options.

Stitches and Stitch Patterns

• Garter Stitch: Used for the main body sections, worked over 97 to 123 rows depending on size, creating a sturdy, textured foundation
• Seed Stitch: Applied as border sections worked over 67 to 75 rows, providing a refined edge detail and visual contrast
• Ribbing: Used for finishing edges, alternating knit and purl stitches (K1, P1 pattern) to create elasticity and definition

Needles and Yarn Requirements

The pattern calls for 7 millimeter needles for the front panel worked with two strands of yarn, and 5 millimeter needles for the back panel worked with a single strand. This variation in needle size and yarn thickness creates intentional differences in fabric density between front and back sections. The yarn specified is Purl Alpaca Medium, a luxury fiber composed of 100% alpaca with a yardage of 77 meters per 50-gram ball. Yarn requirements range from 7 balls for the smallest size (XS) to 11 balls for the largest size (XL). The sample shown in the pattern is photographed in the shade "Alpaca Mist."

Yarn Weight and Fiber Properties

The pattern uses aran and worsted weight yarn categories. Alpaca fiber is prized for its softness, warmth, and lustrous appearance. The 100% alpaca composition makes this waistcoat a breathable yet insulating layering piece, suitable for wearing over shirts or light sweaters.

Tension and Fit

Achieving correct tension is essential for this project. The pattern specifies two different tension gauges: 16 stitches and 23 rows to a 10-centimeter square over stocking stitch using 6-millimeter needles and one strand of yarn, and 12 stitches and 24 rows to a 10-centimeter square over garter stitch using 7-millimeter needles. These precise measurements ensure that the finished waistcoat will fit properly at the intended bust measurements across all five sizes.

Skill Level

Rated as intermediate difficulty, this project requires knitters to be comfortable with basic stitches, tension management, reading pattern instructions, and assembling multiple pieces. The use of two different needle sizes and yarn thicknesses, combined with multiple stitch pattern sections, makes this suitable for knitters with some prior experience.
