I mean no disrespect by this, but I think this looks totally unprofessional.I'm a new ref, and feel I'd drop my whistle. So I made a contraption. A coil wrist bracelet with a loop of ball chain attaching the whistle to the bracelet. So I hold the whistle comfortably, but can drop it when needed. The bracelet has a pretty sparkle to it too - it's kids' jewelry. View attachment 5908
Also, I'm brand new to this forum. It looks like a great place to learn and ask questions. Thanks to those of you who help run this!
