Planning a wedding? No? You might want to reconsider your fear of commitment after a visit to Paper Presentation. The block-wide megastore is a wedding do-it-yourselfer's dream. Their selection of ribbon, stamps, stickers, and sparkly invitation pockets will inspire many more inserts into your mailing than you ever thought you would possibly need. The store also helps you stick to your prenuptial exercise regimen by making you do laps between paper and envelope displays every time you change your mind about which turquoise—Aquamarine, Tiffany Blue, Ocean, Astro, or South Beach—is the right turquoise. Those serious about remaining a bachelor, however, get their own whole section of the store: The back left corner is a scrapbooking wonderland, stocking all the cute little doodads you and your cats will ever need to chronicle life's many whimsies. 23 West 18th Street, 212-463-7035, paperpresentation.com (10011)
