Algae Yarn Recipe - DIY Biodegradable String

This beginner-friendly guide to making algae yarn introduces you to the process of creating your own biodegradable yarn from natural, food-grade materials. Using simple ingredients like sodium alginate, calcium chloride, water, glycerin, sunflower oil, and natural or food-safe dye, you’ll learn how to mix and transform them into a soft, rubbery, and fully compostable yarn.

Perfect for artists, educators, students, or anyone curious about sustainable materials, this guide offers a hands-on introduction to biomaterials and eco-friendly making.

You’ll notice this guide is completely free - because the knowledge of working with biomaterials should never be behind a paywall. I hope it inspires more people to experiment, share ideas, and develop creative solutions to environmental challenges.

If you try it out or adapt the method, I’d love to hear your thoughts! Please share your feedback or creations on social media - @alivemakerspace on all platforms.
