I'm not crafty, but I greatly admire people like my sister who can make magic out of the most mundane materials. That's why I'm intrigued with Etsy Earth, a small portal focused on earth-friendly handmade goods.
I also dig the artisan outlet 1000 Markets. Stunning leather fringe earrings from Lynore Store are made with materials designer Lynore Routte sources from her own clothing, finds in thrift shops or reclaims from the fashion industry. Dwell magazine editor Sarah Rich turned me on to handmade prints created by independent designers in San Francisco on sustainably grown, chemical-free maple.
If you are crafty enough to DIY, here is a great guide. Crafted By Us teaches you how to make your own duct tape purse, among other things. If you covet the purse (like me) but have no crafty inclinations, KMC designs has really well-made duct tape clutches, wallets and bags that I would go so far as to call elegant.
