@Kaarme Yea, but really? No one does that? I have a name plate that has velcro on its back. I sometimes take it off and play with it...and when I'm playing with it I end up scratch any itch that I get using that. Usually the parts that become red and bruised are the back of my hand or my nose. It just feels really good while scratching that I don't even realise that I'm bruising my skin.
@Walter_vi_Britannia That stuff is everywhere, to the point I've bought it by the meter from a fabric store to replace it in gear where it had started losing its properties (since I like to fix stuff if I can). Yet I can't recall I'd have ever caused as much as skin irritation with it, let alone rash or worse.
