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.

People from all countries around the world are invited to join IWCS, enjoy the benefits of membership and discover more about nature's wonder material -- wood! Collecting wood and/or using wood creatively has to be one of the most unique hobby interests that you could ever pick. IWCS members around the world have formed a network for information exchange and mutual assistance.

    - Getting the Word out via Wood Related Shows and Gatherings by Eric Krum#9467 & Mark Peet#9804L.
    In this year of action to increase the membership of the society several of us are working to get word out to the public about the society by participating in wood related shows and gatherings. Results have been positive with many people showing an interest in wood during the show and subsequently joining the society. Setting up an IWCS booth with a display was easy with help from Elaine Hunt and Dennis Wilson. Dennis Wilson recently assumed the job of Show Coordinator, if you know of a show or fair in your area contact Dennis at . Posted 10-28-2016
