There's something about creating a beautiful display of flowers or a blooming garden that is therapeutic on many levels. The mental and physical energy that goes into the activity provides good exercise, and the added beauty brightens up each day.
Or plant some succulents in old drawers? Be still my heart. I really love this idea. The mix of weathered wood, stones and the wonderful texture of succulents speaks to me. I have some old sewing machine drawers that would be perfect for this project.
