My uncle came up with an unusual “folder”, but somehow does not dare to write to you; he considers it a trifle. However, someone also might come in handy: it is easy to manufacture and very easy to use. To make it, need a old spoke from a Bicycle with a length of 24-25 cm and It is bent, as shown, and the folder is ready. This spring-loaded clamp securely holds quite a voluminous sheaf of papers, drawings.
