If you're lucky enough to live in an area where you have access to driftwood, pick some up! There are so many decorative and functional things you can do with driftwood, and it won't cost a cent. And it's a stunning way to bring a little bit of nature into your home for any season. I've been working with driftwood lately for some of the Erthe line products for towel hooks, jewellery holders, and shelving. It's so organically appealing to the senses. Hope these ideas inspire you (click for sources).
