Not too long ago, the beloved Instructables kickball was popped by an overzealous dog. As we are not prone to ever throw anything away (ever), it just lamely drifted around the office as people slowly kicked it about in dissatisfaction from spot to spot. This continued for a while until one day I had the idea to resurrect this ball by cutting it in half and turn it into a hanging plant basket. And, that is precisely what I did. Follows are directions so you can do the same.
