Of all of the items listed in The Knot's registry survey, only one segment grew more popular year over year: grilling and barbecue equipment. A full 43% of couples registered for outdoor items, more than those who registered for luggage (36%) or fine china (32%). "Consider the entire calendar when you register," Forrest says. "Even if you're picking out gifts in the middle of winter, you should still register for barbecue sets and gardening tools -- it will be warm out soon enough." Those forward-looking couples are making a big difference in where people register as well. The percentage of couples registered at Williams-Sonoma ( WSM) grew to 10% from 9% within the past year, while Home Depot registries have risen from 2% of overall registries to 3%. "And think about holidays, too -- if you're registering in June, don't forget to consider Christmas ornaments, menorahs, holiday-themed china, etc.," Forrest says. "Just be aware that some stores won't stock these seasonal items year-round, so you may need to revisit your registry several times throughout your engagement to add holiday-related gifts."
