It is frequently necessary to make sandwiches several hours before they are needed. As they dry quickly they must be carefully wrapped or they will be unpalatable. Wring from cold water two ordinary tea towels; put one on top of the other. An old tablecloth will answer the purpose very well. As fast as the sandwiches are made put them on top of the damp towel; when you have the desired quantity, cover the top with moist lettuce leaves; fold over the towels, and put outside of this a perfectly dry, square cloth. Sandwiches will keep in this way for several hours, and in perfectly good condition. On a very warm day they may be covered all over with moist lettuce leaves; use the green ones that are not so palatable or sightly for garnishing.
