A guide on how to knit a triangular shawl featuring step-by-step instructions and detailed lacework.

Triangular Shawl: A Classic Shape

The triangular shawl is a timeless favorite in the knitting world. Its simple yet elegant structure makes it a perfect project for knitters of all skill levels.

Understanding the Structure

A triangular shawl is elegantly simple in its construction: I view it as a large triangle split into two smaller triangles, with a center spine stitch running down the middle. The symmetry of this design is what makes it both visually striking and easy to execute:

  • Once you chart one half of the shawl,

  • The other half is simply a mirrored repeat!

Increases are the key to shaping this triangular form. Referring to the schematic:

  • Increases are worked at the beginning of the row,

  • The end of the row, and

  • On either side of the center spine stitch.

This method adds 4 stitches every right-side row, giving the shawl its characteristic growth and balanced symmetry.

Cast-On Method: The Garter Tab

The garter tab cast-on is a foundational technique for many shawl patterns, creating a smooth, seamless edge that blends beautifully into the design for a polished look. While it may feel tricky at first, it’s straightforward and highly effective once mastered.

Why Use the Garter Tab Cast-On?

  • Ensures a consistent, tidy edge that integrates seamlessly into the shawl.

  • Provides a balanced starting point for triangular, crescent, and other shawl shapes.

  • Suitable for a variety of shawl styles and constructions.

How It Works

This method begins with a small strip of garter stitch, transitioning into picking up stitches along its edges to form the shawl’s base.

For triangular shawls:

  • The shawl starts at the center top with the garter tab cast-on (see the topmost section of the schematic).

  • From there, the shawl fans out diagonally as you add stitches through consistent increases.

This technique not only provides a seamless foundation but also ensures the shawl is secure and visually cohesive.

What to Expect

In this post, we’ll dive into the foundational techniques for knitting a triangular shawl. We will:

  • Walk you through the step-by-step instructions

  • Offer mindful practices to help you deepen your understanding of the shawl shape.


Shape Instructions

Abbreviations:

  • CO: Cast On

  • K: Knit

  • P: Purl

  • Pm: Place Marker

  • Sm: Slip Marker

  • Yo: Yarn Over

  • RS: Right Side

  • WS: Wrong Side

Set-Up:

  • Cast On: Cast on 3 stitches.

  • Knit the Garter Strip: Knit 6 rows. This creates a small rectangular strip of garter stitch.

  • Pick Up Stitches Along the Edges:

    1. Turn your work 90 degrees to the right

      1. OR Turn the tip of your right knitting needle up.

    2. Pick up and knit 3 stitches along the long edge of the garter strip.

    3. Turn your work 90 degrees to the right again and pick up 3 more stitches along the cast-on edge.

    4. You’ll now have 9 stitches on your needle.

  • Set Up Markers for the Shawl: Arrange your stitches and place markers as follows: K3, pm, p1, pm, p1, pm, p1, pm, k3. (4 stitch markers total).

Working the Body of the Shawl:

  • Row 1 (RS): K3, sm, yo, k until next marker, yo, sm, k1, sm, yo, k until next marker, yo, sm, k3. (4 sts increased)

  • Row 2 (WS): K3, sm, p until last marker, sm, k3.

  • Repeat Rows 1 and 2 until the shawl reaches a depth of 4 inches.

  • Bind off stitches on a RS row.

  • Block the swatch and weave in ends.


Mindful Knitting Practice

Consistency in Edges: Always Start and End with K3

Every row of the shawl begins and ends with knit 3 stitches (k3). This is from the garter tab cast-on originally. This creates a neat, uniform edge that provides structure and makes blocking easier. Think of these edge stitches as the “frame” for your shawl.

Observe the Chart and Written Instructions

Take a moment to carefully examine both the chart and the written instructions.

  • Look for Patterns: Can you see how the increases (yarn overs) are shaping the fabric?

  • Symmetry and Mirroring: Notice how one side mirrors the other, with the spine stitch acting as the dividing line.

Get a Feel for the Rhythm of Increases

As you knit, try to focus on the rhythm of the increases.

  • Increases happen at the edges and around the spine stitch on every right-side (RS) row.

  • As the shawl grows, you’ll find the increases create a natural flow, making it easier to predict and follow the pattern without constantly referring to the instructions.
