I'm looking for a lock that will stop the sliding doors on our wardrobe from opening. Kind of like the "Kidco Sliding Closet Door Lock" - but it's $38 from fishpond - for a piece of plastic with some sticky stuff on the back?

Just wondering if anyone has solved this problem with another product? Or some DIY solution?

We don't have poisons or lethal weapons in the wardrobe, I just want to stop bub from pulling out all our socks and shoes and clothes etc.....
