My mom got a free Cranberry Hot Pad/Trivet as a gift for being one of my charter hosts, but when she got it yesterday, she was really disappointed that it said not to use it on wood?!?! Since her (and probably 90% of the rest of the population's) dining room table is wood, it kind of defeats the purpose of her getting it! Since it's heat-resistant to 675 degrees, why can't it be used on wood?? Does anyone know what that is about? And shouldn't the catalog tell you if you can't use a trivet on your dining room table??
