I absolutely adore this pine cone boutonniere I found this morning on Etsy. A lovely little perfectly-shaped pinecone, some twine, small satin ribbon and a corsage pin for just over ten dollars. If you're comfortable with a pair of pliers and a mini handsaw, you can easily make your own. Create your rustic boutonniere from the "flower" that appears at the bottom of every pinecone. Here's a great guide from Martha Stewart on how to make a pinecone boutonniere.
