I wanted a way to hang LED fairy lights under my daughter's bed as it's a place she often plays, so a string of LEDs makes it feel extra special. These hooks are designed to clip onto the underside of the wooden slats, and then LED string pushed onto the hooks. Once in place it's pretty strong - you'll just need quite a few of them for good coverage.

The clip is designed for a slat approximately 60mm wide, 16.5mm thick.
