Product Description
This unusual shaped afghan is based on the Golden Mean and the Fibonacci Sequence. The shape is known as the Golden Spiral.
The Golden Mean has been used widely for thousands of years, in art and design. It also occurs very often in nature. Items using these proportions ‘look right’ to most people.
Adding the border means that the proportions of the completed afghan are not quite those of the Golden Mean. If you want to maintain mathematical accuracy you can omit the border or mount the spiral on a rectangle of fabric or crochet, as described in the instructions.
It is very easy to making using crochet trebles throughout (UK definition). Only basic crochet skills are needed.
The afghan in the photos was made in DK yarns. It could be made in any yarn though this would change the overall size.
The instructions also contain several variations for more complex use of spirals. Another possibility is to omit the largest sections to create a pillow or wall-hanging.
Golden Spiral Crochet Afghan by Woolly Thoughts
Project Overview
Golden Spiral is a mathematically-inspired crochet afghan or wall-hanging designed by Pat Ashforth and Steve Plummer of Woolly Thoughts. This decorative piece is based on the Fibonacci Sequence and the Golden Mean, creating a distinctive spiral shape that is both visually striking and suitable for wrapping, displaying on a bed, or hanging on a wall. The finished afghan measures approximately 100 cm x 160 cm (40 inches x 64 inches) for the spiral itself, with an overall size of 115 cm x 175 cm (46 inches x 70 inches).
Construction Method
Golden Spiral is worked entirely in crochet trebles using the UK definition. The afghan is constructed in one continuous piece, eliminating the need for assembly or blocking. The single-piece construction method allows the spiral to naturally assume its correct mathematical shape without additional finishing techniques.
Stitches and Techniques
- Primary Stitch: Crochet trebles (UK definition) throughout the entire project
- Construction: Worked as one piece from start to finish
- Finishing: No blocking required—the design naturally forms the correct shape
Mathematical Design Foundation
The Golden Spiral incorporates two fundamental mathematical concepts: the Golden Mean and Fibonacci Numbers. The Golden Mean, also known as the Divine Proportion or the extreme and mean ratio, is a special mathematical ratio that has been used throughout history in art, architecture, and nature. The Fibonacci Sequence, which appears frequently in natural spirals and growth patterns, forms the structural basis of this afghan's unique spiral configuration.
Materials
Golden Spiral is made using DK weight yarn, which provides an appropriate thickness for creating defined treble stitches while maintaining the precision needed for the mathematical spiral pattern. A crochet hook suitable for DK yarn is required for this intermediate-level project.
Skill Level
This project is rated as intermediate difficulty, making it suitable for crocheters with foundational skills who are ready to explore more complex stitch patterns and mathematical design principles.
