Common schach materials include: bamboo poles, other wooden poles or slats, reeds, corn stalks, bamboo mats. Reeds and corn stalks are not always readily available. Seeking ideas for inexpensive schach materials other than those commonly used. (URLs would be appreciated.)
The cRc have previously sanctioned certain varieties of Home Depot bamboo fencing for use as schach. I'm not sure if they are doing so this year.
