Confetti is fun! That is, unless New Year’s Eve is at your apartment. Then it’s a day-after menace. Opt instead for less throwable party accessories, like these Mylar-and-tissue-paper flowers ($23 each at Creatures of Comfort, 205 Mulberry St., nr. Spring St.; 212-925-1005) by local prop-art duo Confetti System. The bouquets make for a festive tabletop centerpiece and house-party motif without the promise of a January 1 spent hungover vacuuming.
