There is a very popular expression in my land that says: "Paper holds everything"; of course it doesn't refer to the paper used for these handcrafted wonders that you show us in your photo, @velimir, but it could be applied playfully. There are the wonders that are done with the ancient Chinese-Japanese art of folding paper known for a while as "origami". There is a not-so-new technique called "papier-mâché" with which I have seen amazing works as well. The products you collect in your photographic testimony are magnificent manifestations of that ingenuity and skill with paper. Saludos.
