If you had wool items displayed at the show, please inspect them to make sure they are free of moths. Linda just discovered a very small moth on the wool neckline of her silk felted tunic!!! She was able to pinch and kill it before it took off in flight. For prevention, she uses cedar wood essential oil, which is applied to strips of muslin hung on the ceiling or shelf above -so as not to transfer the oil to the garment because the oil might stain.
Other herbs that deter moths are mint, lavender, cloves, thyme, and rosemary. Best bet is to store clean items in plastic storage containers.
