In order to implement the types of indoor pastimes previously described, many households wisely maintain a box or drawer full of empty scrap books, blunt scissors, colorful magazine illustrations and calendars, old Christmas cards, beads, modeling clay, sewing materials, construction paper, cutout patterns, maps, marbles, "lost" rubber balls, puzzles old and new, empty cigar boxes, tinfoil, crepe paper, rubber bands, soft pine or balsa scraps for whittling, discarded or partially broken toys (to be repaired and refurbished for less privileged children, community chests, or veterans' organizations), and other useful oddments.
