For example, many traditional Jews refrain from tearing toilet paper on the Sabbath. On the 'observe' side of things, by tearing on the perforations, one is cutting something to size, like preparing strips of leather for the tabernacle. On the 'remember' side of things, doing something different on Shabbat, using already torn pieces or facial tissues, reminds one that this day is indeed different. In the same line of thinking, some people use a favorite, special mug for their coffee on Shabbat, or place bouquets of flowers in each room for the holiday. The essence is to make the day different, separate, beautiful and restful, whatever that may mean to you.
Labor is a craft, but perfect rest is an art.
