I sewed mine on. Just draped them and ran thread through each one individually then together. I don't know how to sew, but this is just running thread back and forth, doesn't have to be pretty, just secure. And I ran hot glue over the thread on the inside to make sure it was all held solid.
I strongly suggest sewing them on unless you want to lose them. They'll slip off while moving around or someone will pull them off.
Some kid kept pulling mine every time I'd turn my back at this YMCA camp gig I did this weekend. Damn kid! If they weren't sewn on, they'd be gone. As it is, I lost a shin tool. I'm not sure if it fell off on it's own or if someone stole it. Oh well...
My scalps make a loop around my arm and hang down in the front. They are all sewn together and I had a snap sewn to the bottom where it connected at my shoulder. So the scalps snap onto my vest and can snap off. Works great.
I like that Saftey pin idea, I have em just hanging there, but after readin the Y-kid story I think ill secure em better
it only takes one kid to run off with them. and I cant move for crap in my suit :facepalm
