What a cute idea: Before going for a walk you take a piece of tape around your wrist (sticky side at the outside! ;-)) and while walking you stick on a lot of beautiful leaves and flowers.
When you’re coming home you have a wonderful nature bracelet.
She seems to have done this in springtime but the fall leaves also look great.
And by the way you can cut open the tape at home and use it for a card ;-))
