When it comes to buying that perfect gift for your soon-to-be married friends, Gretta says to keep two things in mind:

• Choose a gift that will match the couple's taste -- make it about them, not you. Sure, you may love that zebra-stripped blanket or porcelain dog figurine, but you can bet that your newlywed friends will think, "Huh?" right before they re-gift or toss them.

• When in doubt, buy something from the gift registry. Couples spend a lot of time picking out items for their new life together, so you might as well play it safe and buy something you know they want.

Maybe you've procrastinated and there's nothing left on the couple's registry? Or perhaps you just want to get something really personal that's not on their list? Gretta's got you covered with these gift ideas.

Cordless vacuums can be found on most registries, so why not kick it up a notch and upgrade your gift to a hipper, super sleek stainless steel vaccuum?

Every couple can use coasters, so why not personalize them with pictures of the couple and their friends and family? Guests will love looking at and using photo coasters, so you'll never have to worry about nasty rings on your coffee table!

Seasonal dishes can be used every year around the holidays, and many couples might not think to add something like this to their registries.

Lovopoly! It's a personalized game board based on Monopoly. You can customize the board with pictures, and all of the properties can be places or things that have special meaning to the happy couple.

A couple might not register for his & her robes, but you can give them a little bit of the spa treatment with luxurious monogramed bathrobes.
