I've never taken more care than simply putting them in paper in a
cardboard box in an unheated room. Better gardeners seal them in a
plastic box (making sure they're perfectly dry first, and maybe putting
in those little silica gel packets you get with cameras and such) in
the fridge or even the freezer.
