Pittsburgh Satellite Reef

Now Open in the Charity Randall Gallery at the Carnegie Museum of Art!

View the Satellite Reef November 4, 2023- January 25, 2025!

The Pittsburgh Satellite Crochet Coral Reef project is a unique community initiative that encourages people to come together and create something beautiful. The project involves many people creating hyperbolic shapes using crochet and combining them into a singular coral reef that will be displayed in the Carnegie Museum of Art. It is an amazing opportunity for people from all walks of life to get involved and make a difference.

The project has been gaining momentum since its inception, with more and more people joining in on the fun. By participating, individuals can not only contribute to the beauty of the reef but also learn new skills such as crocheting and working with others as part of a team. This project is an example of how community participation can bring about awareness of environmental issues and create positive change in our society.

Kid Ewe Knot is thrilled to partner with The Carnegie Museum of Art on this Satellite Reef in cooperation with the Institute for Figuring. In addition to community based workshops, we are offering times to gather in shop and work collaboratively with other enthusiastic crocheters.

More of Your Questions Answered:

What skills are necessary to crochet Hyperbolic Shapes?

If you can chain and single crochet, you are golden! If you do not know the basics, we do offer private, one hour lessons to get you started. Unfortunately, due to the wide variety of skill levels and the amount of people at our larger workshops, we do not offer beginner lessons at those times.

What Materials Should We Use to Crochet?

This is a great project for using up all those pesky leftover bits in your stash! Novelties are wonderful additions to your creations. Use acrylic, wool, cotton, rayon, any weight, any color. Use the appropriate hook for the yarns you choose. Don't be shy, experiment! Hold yarns together for fun texture and color outcomes. Make an environmental statement, incorporate plastic or other ocean trash into your coral. 

How to Crochet Hyperbolic Corals

Read more about the Crochet Coral Reef project (we have pamphlets in shop with all the information you need) and learn how to make your own hyperbolic crochet.Try the shapes in This Guide.

Any style, material, or color of yarn can be used, and creativity and experimentation are encouraged! If you are brand-new to crochet, we recommend purchasing medium-weight (4) yarn and a 5.5mm (or I/9) crochet hook.

What other types of shapes can be crocheted for the reef?

Plenty! Would you like to make Brain Coral? Tube Coral? Sure! What is not included are animals ssuch as sand dollars, starfish and Nemo or Dory. (That would be fish in general!) Inspiration images from coralreef.org

About the Crochet Coral Reef Project

The Crochet Coral Reef is a research-oriented project by sisters Christine Wertheim and Margaret Wertheim of The Institute For Figuring. Residing at the intersection of mathematics, marine biology, handicraft, and community art practice, the project responds to the environmental crisis of global warming and the escalating problem of oceanic plastic trash by highlighting not only the damage humans do to earth’s ecology, but also our power for positive action. The Wertheims’ Crochet Coral Reef collection has been exhibited worldwide, including at the 58th Biennale di Arte aka Venice Biennale, Helsinki Biennial, Hayward Gallery, London, Science Gallery, Dublin, Museum of Arts and Design, New York, and the Smithsonian’s National Museum of Natural History, Washington, D.C. The project also encompasses a community-art program in which more than 20,000 people around the world have participated in making 50 locally-based Satellite Reefs—in New York, Chicago, Melbourne, Ireland, Latvia, Germany, UAE and elsewhere. The Pittsburgh Satellite Reef on display here is the latest addition to this ever-evolving wooly archipelago.
