Simple can be so good! Here are nice examples of using vintage objects as containers for tabletop trees, especially the wine crate on the left. Try perusing antique markets for unique editions for your christmas decor and keeping it simple makes it comfortable + sustainable. Planting a small evergreen outside after Christmas seems manageable too.
A good resource for vintage inspiration is Greenhouse Design Studio, which was featured in this month’s issue of Whole Living. They have a collection of new and vintage finds plus a whole host of information on green living on their site.
Hope this inspires you to give new life to something old. Also, take a peek at my christmas cheer Pinterest board for more inspiration.
