If you buy your table salt or dishwasher detergent in cardboard boxes, save the little metal pour spout. If you flatten the triangular "stabber tabs" hat hold it into the box, and turn it on its' side, they are the perfect size and shape to hold magazines or books upright on a desk or shelf. There will be no bottom, but if you are gluing everything in place, who cares? Otherwise, just make it a bottom with a bit of cardstock glued in place, then paint the whole thing whatever finish you want.
For an office desk I just left them plain silver metal and stuck on some mini post-it notes and decorative "magnets" with some of my favourite workplace sayings like 'Teamwork means nobody has to take the blame.'
