Here are a few registry trends which caught our eye:

Bathroom spas - Though the bathroom has hits place in the traditional registry, couples want to make the bathroom more of a spa experience and are equipping it with luxury features, such as heated towel racks and fountain shower heads.

No Gifts, Just Give - Some people who don't want material gifts ask guests to give to their favorite charities. Websites such as the I Do Foundation and JustGive organize guests' donations to help a favorite charity.

Sporting goods - Grooms are catching on to registry fever but might not care about decor as much as active gear that the couple can share, such as mountain bikes, golf clubs and tennis rackets.

Museums - It's very new and not yet a trend, but couples can register at some museum shops for artwork, books and home decor. Check with your favorite museum to see if they offer a registry.

Wine - More popular with older couples, some people register for a wine collection and even the wine cellar. See retailer WineEnthusiast.com.

That brings me to the question of etiquette - are these registries considered impolite? Etiquette experts say these registries aren't anymore offensive than the traditional ones. Please note, however, that there is one decidedly tacky way to spread the word - never, never, never put it in an invitation, as no one is obligated to get couples a wedding gift.
