Khadi Paper Book
Khadi rag papers are made from 100% cotton rag. Cotton rags have longer fibres than linters which are the shorter fluffy cotton seed fibres commonly used in papermaking. Genuine rag papers are rare and it is the fibre length of this raw material that gives Khadi rag papers their exceptional strength and durability.
