As for the double-thick potholder I made that weekend, too. It's gone missing. I think it must be packed away in my dog sitting gear still, but I've been too lazy to look for it since it's been too hot for me to make soup anyway. (It's been >80F and 50-85% humidity for the last week here.) When I find it, you have my word I'll post it along with an image of my famous Zuppa Toscana.
(Man, I'm hungry now...)
