Thanks for doing this, and I'm glad to see such a strong response.
I'm pretty much a constant thriftshopper--it's cheap entertainment with my kids, and it's how I get raw materials for my art purses, so I can justify it (kinda). Recently one of our local shops had a ton of yarn, including a big bag of vintage Italian mohair--all "tangerine"--for $1.99. This hat was made from some of that, and from a skein of even brighter orange acrylic yarn I found at a yard sale. I've been wanting to play with hyperbolic crochet more, so.... I think this will be the start of my Halloween costume -- I'm planning another crocheted creation, like last year's garden, but this year I'm thinking "wearable coral reef." Stay tuned.
