There! I finished my contribution to the Sidney Reef Hyperbolic Crochet Coral exhibit. Now I have to mail them off to Australia:
The whitish one is made of plastic shopping bags, the blue and green is from leftover acrylic yarn from a bedspread I made and the brown one is made from 100% cotton yarn from the "discontinued" section in the basement of Romni Wools (on Queen Street West...GREAT STORE!)
I love the technique used on the brown one. I'm going to use it to make other things now.
