Being green comes in many fashions—it's not all hybrid cars and compact fluorescent light bulbs (although those are great, too). One Australian stay-at-home mum is wearing her environmentalism on her sleeve, literally, and has invited the blogosphere to join in.

In 2006, Nichola Prested started Wardrobe Refashion and welcomed fellow crafters to take the refashion pledge. Their vow? To abstain from buying manufactured clothing items for two, four, or six months.

The only "new" clothes "refashionistas" can have are ones they make or recycle from pre-loved items. Exemptions are allowed for undies and shoes, and crafters can buy some new fabric and yarn, but the emphasis is less consumption, more creativity.

This collaborative blog and Flickr group fast became a hit, and each new refashion cycle has added more and more participants. We talked to Nikki about her sustainable style.  Read the full profile...

Though few (if any) horses trot through the streets of Portland today, their memory has not galloped off over the hills. Apparently, rings for tethering the gallant beasts still dot the Oregon city, waiting vainly for their four-legged friends to return. Thanks to an artist named Scott Wayne Indiana, they wait no longer. In late 2005, Scott "tied his first pony to a horse ring" in the downtown Pearl District. Scott's steed was miniature and cheap and plastic, but its mane flowed just as freely and its hoofs pranced just as happily as any warm-blooded equivalent. (Or so we like to think.) Anyway, since that day, many Oregonians have joined in the project's mission to utilize the city's tether rings once more. View photos, examine the municipal map, and perhaps tie a few stallions of your own. But whatever you do, please, don't resort to horse thievery. Portland deserves its stable of pretty ponies.

It doesn't take much to enlist in The Envelope Collective. Three simple steps will land you in their warm embrace:

1. Turn an envelope into a piece of art.
2. Stamp it.
3. Mail it to one of the Collective's three thoroughly disclosed locations.

Assuming neither snow nor rain nor dark of night interfere, you should soon see your handiwork displayed in the group's online gallery. This "collaborative experiment in art" welcomes graphic squares and squiggles, goblin renderings, rock star tributes, and penguin portraits of all kinds. Whether you fancy collage or illustration or 55-word tales, you will find a hearty welcome here. And if you feel like contributing multiple times, go right ahead. Some mail-art activists are nearing 100 deliveries. Long live the Collective!
