I have been drying oregano, sage, mint, basil, thyme and rosmary for some times. Depending on the herbs I either hang them upside down in a dark place (mint, oregano, sage) or I use an electrical dryer machine. I found a rather unexpensive one on amazon. The advantage of using the dryer is that it works fast and preserves the aroma of thin leaves such as basil. It also helps with herbs that normally require longer time to dry (rosemary, sage) and tend to break.
