The traditional way is to tie them by the stems in small bunches and hang them upside down from the rafters until they are dry.
It's also a good idea to place paper or some kind of container under them to catch the leaves that fall off early.
If I'm not using the dehydrater I usually bundle them and hang them upside down in the garage. My brother came over one time and saw them and asked me if I was trying to repel vampires.
