My favourite idea for a birthday present is something that's unique. Giving them a gift that they can't simply go to a store and buy makes it that extra special, and shows that you've got them something original. This also prevents the recipient from working out how much you paid so if you're being a tightass they will never know. Some of the best unique presents are things you can wear. For a girl, giving unique jewellery as a gift is always a great way to put a smile on her face. It may be a hand made necklace or even rings that have a creative feel. Because the piece of jewellery is one of a kind, it will stand out and she will always remember you for it.

One of the most popular things at the moment are mobile phones. And the hottest type of phone on the market is undoubtedly the iPhone with their easy to use system, and thousands of applications to make things more convenient for their users. So for a birthday present, why not consider iPhone cases for your friends. There are lots of cool designs and you can even get your own image printed onto the case. It's the perfect idea for a loved ones gift. Imagine giving your girlfriend an iPhone cover with a photo of you on it. She'll be absolutely wrapped, until you cheat on her and you break up, then she's got a constant reminder of the jerk who screwed her over. Maybe put a nice photo of a kitty on it instead!

If the person celebrating the 21st lives in the country, chances are she's just had a baby. In this case, a perfect gift can be baby clothes or accessories. Nothing says happy birthday to a single mother with loose morals more than a teddy bear suit for her little bubba or a Sesame Street mobile hanger. These days there are so many great accessories to choose from including baby sleep bags, cuddlewrap, a playtime bouquet or even nappy bags. Let her know that you care.

Sometimes for a birthday, the recipient is sick of receiving multiple gifts that are all the same, such as 10 bottles of red wine, multiple photo frames from Dimmeys and an excessive number of beer glases. I know we like our alcohol but there's only so many we can use at any one time! Therefore some people decide to create a gift registry to send out to all their friends before the big event. That way, when buying a present, only things that the person actually wants will be bought, and only one of each thing. A gift registry is a great idea because it allows the person to list exactly what they want and need, and people buying can choose an appropriate gift according to their budget and taste. The only thing is, don't leave it until the last minute or you'll be left buying the oven mitts!
