You might check to see if there is a place where people can donate craft and arts supplies near you. We have one called ReDux, where people can donate arts and crafts supplies that are then sold at a discount to artists/crafts people.
Also, you might check to see if there is a non-profit organization that teaches arts and crafts we have one of those here that will take tools and such.
Our police department has a partnership going with another non-profit where the local police have craft day get togethers with local youth. I've donated a lot of stuff to that as well.
Finally, there may be a local Boys or Girls club that would be happy to have the material for their arts/crafts classes.
