Drying herbs

A couple of weeks ago I dried more herbs. Sage, Lemon Verbena and Lemon Balm. I also opened up the herbs I had hung to dry a month or so ago and put the dried herbs into tiny jam jars. Everything worked great accept for the tarragon...which smelled icky and was black. So I will have to search the net to find a better way to dry that. (If anyone out there knows let me know!)
