This is my contribution to the Thursday theme "summer treasures".I don't have my colors at home so I had to be creative :)
When I was working in Zaragoza many years ago we did a lot of origami. I even learnt how to fold Nils Holgersson on his goose (Swedish children's book character). Can't remember how to do that though.
What you need: a piece of paper and some crayons! Don't use oil pastels as I did because they smudge too much.
And then you need to do some folding and unfolding too of course..:)
