Don't ask me how, but I have a lot of corks. It seems wasteful to just throw them out. Some years ago, I saw a wreath like this, and the answer became obvious: Make a wreath.
The base is a straw wreath from a craft store. Put some fishing line around the wreath as a hanger before you put the corks in. Stick a round toothpick in the base of a cork (not as easy as you might think; use a hammer and nail to make the hole before you try to put the toothpick in) and the other end of the toothpick into the straw. I prefer to have the red end of the corks showing for red-wine corks. Make a gazillion of these and stick them into the wreath in a pattern that you like.
Then, drink more wine so you can make another one.
