Spooly Spool
With the relative success of the Hooky hooks, I extended my hanging from shelf range to include my wire spools. I wanted to be able to remove the spools individually and make the hanger generic enough to take the 2-3 sizes of reel I have. This design has a sturdy interlocking cross bar strong enough to hold the reel and the hooks are snug enough to stop the bar jumping out randomly. (svg here)
