Pineapple, lemon or orange juice may be added at pleasure.

Sandwiches prepared from entire-wheat bread, with fig or date fillings, are particularly wholesome for the children's luncheon basket.
When a particularly aesthetic sandwich is desired, wrap the butter that is to be used in spreading the bread in a napkin, and put it over night in a jar, on a bed of violets or rose petals; strew more flowers over the top and cover the jar tightly.

If meat or fish is to be used as the basis of the sandwich, substitute nasturtium leaves and blossoms, or sprigs of mignonette, for the former flowers.
Fancy butter makes an attractive filling for a sandwich; it has also the merit of being less often in evidence than many another filling.
Sandwiches, except when vegetables and dressings are used, may be prepared early in the day, placed in a stone jar, covered with a slightly dampened cloth, and set away in a cool place until such time as they are wanted.

Or, they may be wrapped in paraffine paper.

Still, when convenient, it is preferable to have everything in readiness, and put the sandwiches together just before serving.
