Was googling crafts to do with toilet roll tubes (I teach kids English on weekends!) and I came across this
I would never expect something so serene and quite beautiful sprouting from an ugly toilet roll tube like this.
Tracing its origins I found this work to belong
to a Japanese artist called Yuken Teruya.
Another amazing project she did involving everyday shopping/paper bags, this photo is of the inside of the bag in question.
