I have a habit of seeing something I like in a shop and thinking, "I could make that."
In the case of the cork wreath, I was right. I sweet-talked a friend who'd been saving corks for a while, found these instructions online  and got down to business with my hot glue gun.
I followed the instructions almost exactly and thought the wreath turned out well (See the photo below.) The bow is made from 10 or 15 strands of twine tied together into one bow.
Things I didn't expect: the wreath to require huge amounts of hot glue and corks. I used about 40 hot glue sticks and kept asking my friend, "Can you bring me more corks?" Now I'm making her her own wreath, because I hot-glued my way through a big chunk of her cork collection quickly.
If you like the wreath and aren't scared of hot glue (and if you can keep your fiesty cat away from the corks - they're perfect for batting through the house), try it. It's pretty easy.
