International Wood Collectors Society

A Dedicated Group of Wood Collectors and Crafters

Welcome to IWCS - Advancing Information on Wood Since 1947

Founded in 1947, the International Wood Collectors Society is a non-profit Society devoted to distributing information on collecting wood, correctly identifying and naming wood specimens, and using wood in creative crafts. Although the founders started IWCS with a strong emphasis on academic collecting of wood species, the availability of such a variety of wood and its inherent beauty quickly lead to crafting.

All articles posted on this website are the expressed opinions of the contributing author(s), and not necessarily that of IWCS nor the officers of the International Wood Collectors Society.
