Hexagonal Grey Starburst Knit Afghan in Bernat - Downloadable PDF

Hexagonal Starburst Knit Afghan by the Bernat Design Team

This Hexagonal Starburst Knit Afghan is a free, downloadable PDF pattern created by the Bernat Design Team. It produces a large, striking blanket or throw measuring approximately 54" x 62" (137 cm x 157.5 cm), making it a generous, couch-ready piece ideal for home décor or gifting. The finished design features a bold starburst motif built entirely from geometric triangles arranged into a hexagonal composition — a visually impressive result achieved through surprisingly accessible construction methods.

Design Structure and Construction

The afghan is not knitted in one flat piece. Instead, it is cleverly assembled from 6 individual Strips, each Strip being made up of a series of triangles knitted in sequence. This modular, strip-based approach is a hallmark of geometric knit blanket construction and makes the project far more manageable than working a large piece all at once.

• Base Triangle: Each Strip begins with a Base Triangle, which is cast on (22 stitches) and worked back and forth in rows across the needle.
• Subsequent Triangles: Each additional triangle within a Strip is started by picking up stitches along the edge of the previous triangle, creating a seamless, continuous strip of geometric shapes without the need to cast on fresh each time.
• Assembly: Once all 6 Strips are complete, they are sewn together during finishing to form the full hexagonal starburst layout shown in the diagram included in the pattern.

The color placement across the strips is guided by a diagram included in the PDF, which directs the knitter to use specific colors for each triangle. This is what creates the radiating starburst illusion — a sophisticated visual effect achieved through careful, planned color sequencing rather than complex stitch work.

Techniques Used

Despite its impressive geometric appearance, this pattern is rated Easy (Beginner-friendly), making it an excellent project for newer knitters looking to build confidence while producing a professional-looking result. The techniques involved include:

• Casting on — a standard long-tail or knitted cast-on of 22 stitches to begin each Base Triangle
• Picking up stitches along the edges of completed triangles to begin new ones within each strip
• Working back and forth in rows on a circular needle, treating it as a straight needle
• Shaping through decreases — the triangles are shaped by working decreases on alternating rows until only a few stitches remain
• Seaming / sewing strips together during the finishing stage to assemble the full blanket
• Adding fringe — a simple knotted fringe finish using cut strands of the Main Color yarn

Stitches Used

The stitch vocabulary in this pattern is minimal and beginner-appropriate. The entire fabric is worked in garter stitch (knitting every row on both right-side and wrong-side rows), which gives the blanket a pleasingly ridged, reversible texture that lies flat without curling — a practical advantage in blanket construction.

The shaping stitches used are:

• K (Knit) — the foundational stitch used throughout
• K2tog (Knit 2 Together) — a right-leaning decrease used to reduce stitch count and shape each triangle
• K3tog (Knit 3 Together) — a double decrease used to close off the final stitches at the tip of each triangle
• Kfb (Knit into Front and Back) — an increase stitch listed in the abbreviations, used as needed during construction

The gauge for this pattern is 7 stitches and 16 rows = 4" (10 cm) in garter stitch, which is a relatively open, relaxed gauge well-suited to the super chunky yarn weight used.

Materials: Yarn and Needles

This afghan is designed specifically for Bernat® Blanket™ yarn, a beloved super chunky (weight category 6) yarn known for its ultra-soft, chenille-like texture and satisfying stitch definition. The pattern calls for five colors across the full blanket:
