Each of the three wooden fir frames has a stainless steel mesh screen and four legs that act as spacers when they are stacked. The Stacking Wood Herb Drying Set is perfect for small harvests of aromatic summer herbs so they can dry completely for fall and winter use. It’s also a great tool for drying flowers like chamomile and bee balm, and useful when blending teas from the home garden. The set is easy to assemble, and easy to clean, but it’s meant for indoor use only. Simply cut the stems and flowers of the desired plants and lay them to rest on this attractive rack. The assembled set measures 44.5 x 31 x 18cm (17½ x 12¼ x 7″).
