Christien Meindertsma knit these giant rugs with wool from a sustainable sheep ranch. Each hexagon swatch below represent the yield of one sheep. This is part of the Design for a Living World exhibit at the Cooper Hewitt Museum in NYC which is showcasing products made using sustainable materials from around the world.
I need giant knitting needles like hers!….
It’s like one giant scarf!!

I knit. And I want to do this!!!!!!
What kind of yarn did you use?
I unfortunately did not knit this. The artist, Christien Meindertsma, did. She made her own yarn and needles for this project. Good luck though on your quest to recreate this rug!
ack! this is beyond incredible.
