One of the many things I love about origami is that there are so many resources out there that you can get away with spending next to nothing, regardless of your level. This is very different to many other hobbies, where the main limiting factor of progress is money and whether you can buy the latest generation of equipment or not. Origami is not like this at all. While there are certainly more expensive papers and books out there, some simple double tissue and a crease pattern can get you folding some of the most difficult origami around, not to mention all the diagrams and tutorials that can get you to this stage. This page lists some of these resources, though it barely scratches the surface of what’s out there.
