We have what seems like a MILLION spare belts at the dojo, which is why we finally decided to part with some of them.
I love the "tying stuff to the car" idea. My husband is going to get such a kick out of that...but then what would we do with all our old climbing ropes!??!? (which we already keep in the backs of our cars to tie stuff down with.)
I'll probably end up trying to sew through them, just because I'm stubborn like that. I'll keep you posted.
