Most (though not all) paper is made from wood. Logs are stripped of bark, chopped into very small pieces and then pulped. The pulping stage is important, for at that time various chemicals and things like clay, or old rags, or even straw, are added, which determine the quality, colour and smoothness (or roughness) of the finished paper. Once pulped, the paper is rolled into sheets which are dried out before being cut to required shapes and sizes.
