It's a strange thing but possums are a protected species in Australia but an environmental threat in New Zealand which has a budding industry in producing soft, lightweight and extra-warm possum fur yarn.
The hat above was made of a handspun 50:50 possum fur/merino wool blend yarn bought from a New Zealand fibre artist on eBay.
I made the above hat as a belated birthday present for my husband, just in time for the Australian summer. The weather is predicted to hit 32 degrees Celsius (about 90 degrees Fahrenheit) tomorrow.
I still have a fair bit of yarn left so I may end up making a matching hat for myself.
