Manufacture

Traditionally, globes were manufactured by gluing a printed paper map onto a sphere, often made from wood. The most common type has long, thin gores (strips) of paper that narrow to a point at the poles, small disks cover over the inevitable irregularities at these points. The more gores there are, the less stretching and crumpling is required to make the paper map fit the sphere. This method of globe making was illustrated in 1802 in an engraving in The English Encyclopedia by George Kearsle

Modern globes are often made from
