Our house is covered in hooks, including two hooks in the roof in our bedroom. We found the most delightful wooden + wire hot air balloon (similar style to those vintage style bird cages you see around the place) that I would have loved to have hung from the ceiling, but we were wise little shoppers and saved our pennies instead.
So in its place, I made a origami crane mobile. I folded the cranes from pretty paper, threaded them onto sewing thread and tied them to a stick I found in our garden.
Sitting in that chair and watching them slowly twist in the breeze was the most calming moment of last week.
