Whenever I get really dry hands and can't do even a classic plam I take a hand full of change or the coins I'm going to be using, hold them in my fist and blow hot air into my hands. This usually get my hands in right condition for performing and it gets the coins all warmed up too

. Or I keep both hands in my pocket and it gets everything all warmed up and ready to go.
Or if you prefer, I bought Golden Touch Advanced Skin Care from ellusionist. It's all natural so you know it's safe to use. I'm not sure if they still sell it or not but this stuff works great. IT's awesome for your cards and coins. It doesnt harm your cards at all nor your hands. Penguin might even sell it I didn't check.
