Usually the flowers are air-dried for a couple days or long enough for the outside to feel dry but the interior is still moist with pliable stems. Then they're put into bins for a few weeks of slow drying...aka curing. But bin-curing is usually only done when there are large amounts involved and curing in large glass jars for smaller amounts.
