I've been collecting wine corks for a little while now, and I hope to make a wreath one day. One like this one below from Living Savvy.
I saw one just like it in a friends house in the spring. I loved it and started saving my corks ever since. I will be sure to post my work in progress when I start making the wreath. I know it'll take a lot more corks than I have.
I was thinking about starting it when the jar got full. That shouldn't be long with how much I love my wine.
