We adore things made out of unexpected materials, like this ode to knitting made from sterling silver wire, the Knit Me Something Ring ($30) by wearthou. It also comes in necklace form, but we like the ring. This is an amazing price for such a quality-made piece. The artist has soldered the band, yarn, and knitting needles together. They even handmade the band themselves, so they'll make it in any size you like. The stated creation period is only four days (after payment), though. So it won't significantly hold up the arrival of your brand new bling. Don't know your ring size? There's a handy helper on the product page. Be sure to check out the rest of wearthou's shop because it's freaking fantastic!
PS - We ran across this pretty awesome coffee cup. No, really. You have to check it out!
