I discovered this use of saw dust for making sculptures by an accident, saw dust fell into my wood glue container and I removed it from the container and once it was dry it was rock solid and can be carved like wood. When I was kid I used to make paper mache with wood glue and paper pulp so this challenge inspired me to use it for making sculptures from saw dust mixed with wood glue(Brand Fevicol) it has produced some great results and some of friends even want it. I am looking for mass producing it by wood casting it so that I can give it to my friends and relatives as a gift for this gifting season.
Anyone can try it out and it does put to use a large quantity of wood dust, it does get messy though!
I have attached pics of few crafty items that I made with it recently.
