Mending Tears and Infilling Loses
Paper inherently is fragile and when carelessly handled or subjected to poor conditions will tear and develop losses. As paper ages, it becomes more acidic and brittle. Tears can be mended by different methods. The most common method is to close and reinforce the tears with a thin strip of Japanese (bast fiber paper) using an archival water-soluble paste.
Larger losses can also be repaired with Japanese paper, but a more efficient, and aesthetically pleasing method to in-fill large or numerous areas of loss is by Leafcasting. A process that I have developed an expertise in, and have taught around the world. It is a process that fills losses with a sympathetic, toned paper-pulp. The newly cast paper is comparable and blends with the original paper. It also allows all tears and holes in paper to be filled in one step that reduces the time and cost to repair extensively damaged paper.
