I’m trying out the idea, from another thread, for using tennis balls with holes drilled in them to help make the joints on the corners of a cheap bamboo fruit cage (its not my fault, I never had enough Lego as a child).
I was really pleased to discover how easy it is to drill holes in tennis balls, so that they are the same width as bamboo canes, but I would love to know how many other people have had a go at this sort of thing and any of the pit falls I have to look out for?
