Keep in mind that with cedar oil, you have to look out for it actually staining cloth. I use the oil, too, but I wouldn't put the impregnated blocks up against anything, even after drying. Also, it's pretty damned strong (fragrant). As for storing fabric, why have it in airtight plastic? It needs to breathe and get a little moisture. I keep it in a zippered canvas bag.
