A Spool of Blue Thread: A Novel by Anne Tyler:
Years ago, when the children were small, Abby had started a tradition of hanging a row of ghosts down the length of the front porch every October. There were six of them. Their heads were made of white rubber balls tied up in gauzy white cheesecloth, which trailed nearly to the floor and wafted in the slightest breeze. The whole front of the house took on a misty, floating look. On Halloween the trick-or-treaters would have to bat their way through diaphanous veils, the older ones laughing but the younger ones on the edge of panic, particularly if the night was windy and the cheesecloth was lifting and writhing and wrapping itself around them.
