This story on Boingboing about Artist Nina Katchadourian who tried repairing spider webs with thread, but her efforts were rebuffed: “My repairs were always rejected by the spider and discarded, usually during the course of the night, even in webs which looked abandoned.”

Of course all sheddies know that spiders and their webs are a sacred part of the shedworld. and should not be tampered with.
