I've seen lots of clever ideas using wine corks for home or wedding decorations. When I found a big bag of corks at Goodwill I scooped it up and figured I would try a wine cork board.
I started with a plain wooden picture frame and painted it white. Preferably you would just use the picture frame backing for your cork board, this one did have one so I used a thick piece of cardboard and glued it in place.
Then I started playing with the arrangement of the corks. You want to figure out your pattern before you start gluing them down.
Then staggered them:
You can easily cut the corks with a serrated knife to fill in any gaps on the edges. Since mine were pretty minimal I decided to space the corks so there was a little border instead.
I used my hot glue gun and started at the bottom left corner, working my way across. I continued up each row until they were all secure. If you wanted, you could glue each pair together first and then glue them to the board.
I added a few flowers and it was done!
