TL;DR
An extensive new guide offers detailed instructions, patterns, and mathematical formulas for making homemade juggling beanbags. It aims to help hobbyists craft precise, custom-sized fabric balls.
A comprehensive guide on designing, assembling, and sewing fabric sphere panels for homemade juggling beanbags has been published, offering detailed patterns, mathematical formulas, and assembly instructions. The guide aims to assist hobbyists in creating precise, custom-sized balls for juggling, footbags, and other purposes.
The guide, authored by an experienced hobbyist, spans over 750 pages and is divided into multiple PDF documents, each focusing on different panel structures and design variations. It includes ready-to-print patterns in six sizes, formulas for scaling to other sizes, and detailed instructions for drawing panels both by hand and using CAD software. The designs incorporate curved edges and modified face shapes to improve spherical accuracy, with some patterns developed through extensive experimentation since the mid-1990s.
The author emphasizes accessibility, providing step-by-step instructions suitable for beginners, while also including advanced mathematical explanations for those interested in design improvements. The guide covers fabric selection, stitching techniques, and assembly layouts, along with numerous visual examples and color arrangements.

Evolution of Fabric Ball Design and DIY Juggling
The hobby of making fabric juggling balls dates back to the mid-1990s, with early designs like the orange peel ball and dodecahedron. Prior to this guide, there was little comprehensive documentation on pattern sizing or shape optimization for homemade balls. The author’s previous experiments and subsequent editions reflect ongoing efforts to refine design accuracy, driven by community feedback and personal experimentation. The latest edition, published in August 2022, introduces new patterns, improved shapes, and a split-format for easier navigation.
“My goal was to create a resource that makes it easy for anyone to print, cut, and sew precise fabric balls, regardless of their technical background.”

Remaining Questions About Design Optimization
While the guide provides formulas and experimentation insights, it is not yet clear how these designs perform across all fabric types and sizes, or how they compare in durability and balancing performance. Further testing and user feedback are needed to validate the patterns in broader applications.
Next Steps for DIY Ball Makers and Designers
Readers and hobbyists are encouraged to experiment with the provided patterns and formulas, share their results, and suggest improvements. Future updates may include additional panel designs, more precise shape modifications, and community-driven feedback to enhance the guide’s accuracy and usability. The author plans to continue refining the patterns based on user experiences.
Key Questions
Can I use different fabrics for these patterns?
Yes, the guide offers advice on fabric selection and how different materials may affect the final shape and durability, but testing is recommended for best results.
Do I need special tools or software to draw the patterns?
Basic tools like scissors, sewing needles, and thread are sufficient, but CAD software like SketchUp can be used for more precise pattern drawing, as detailed in the guide.
Are these patterns suitable for professional manufacturing?
The patterns are designed for hobbyist use and customization. For mass production, additional considerations like material consistency and assembly automation would be necessary.
How long does it take to make a beanbag using these patterns?
The time varies depending on experience, but most hobbyists can complete a ball within a few hours, including cutting, sewing, and filling.
