Renewing Vows

The most common thing I hear from a Bride and Groom after a wedding is "I wish we had done this/that"! Some couples wish they did things simpler and others wish that the cake was different, or the wedding was on a beach and the brides dress had been a colour instead of white. A Renewal of your Vows is a great chance to do things differently.
Personally, I would not tell anyone that it was happening. The invite would go out and it would be a shock to everyone. We would only have less than half of the guests that we had at our wedding, it would happen on the beach and my dress would be short and sweet. Oh, and a lolly bar would be available and I would ask everyone to wear the same colour.

The "Decade" Party

Everyone has been to at least One Decade Party. Where the Party Host chooses a past set of 10 years and gets everybody to dress in the fashion that made that era a time to remember. The most popular themes I have witnessed are 1920's, 1950's, 1960's and 1980's. With the clothes, hair and music all making a comeback in one night it is hard not to have a laugh and a bit of fun.
Just remember, as the host, you MUST research the decade and not just assume that you know what happened and what was in style. For example, big mistakes are made when you think you know the 1920's but you end up with a 1930's party.
Also, it is helpful to your guests (that don't know your chosen decade to well) to put some ideas and suggestions on you invite. Famous People, popular movies and music or even a TV family.

Baby Gender Reveal

The best way to reveal the gender of you baby. Invite the family over and have a cake iced in white ready to go. When everyone has gathered cut the cake and reveal the colour.

The Wedding Cake

Weddings, on the whole, have remained as one thing - Traditional. But the one thing that took to evolving first was the wedding cake. No longer a two tiered fruit cake with marzapan, ribbon and a stiff looking couple on top. Now you can find, and even request, any kind of wedding cake you desire.
A tiered wedding cake is still at the top of the list. Traditional and simple! But now variations on the traditional are becomming more popular such as Cupcake towers, Grooms cakes, moving cakes and even ones that have firworks comming from the centre of the cake.

The Twilight Inspired Wedding

The best way to describe the Wedding in Twilight is 'Romantic Earth'. Everything is based around Nature and Love.
Flowers, Candles, Fairy Lights, a lot of whites, reds and greens and a relaxed elegance.

The Halloween Party

When most people think Halloween Party they think Costumes and that's about it. But the host of a Halloween Party has so much more to think about. Food, decorations, music, effects, etc. Halloween Parties can be at any end of the spectrum. You can have a very simplistic party where everyone dresses up and you have themed food. Or you can completely deck out your venue with every scary decoration you can find, even add the effects of smoke machines and Dry Ice and have Haunted House sound effects going on in the background. Itunes has a lot f these sounds for your Ipod/Iphone.

The Baby Shower

My Sister-in-Law has just given our family the best news of the year. She is Pregnant! So my mind (being the one track planing mind it is) has gone into Baby Shower Mode.
The only party I know of that only has one theme is a Baby Shower. The Baby is the main subject of any Baby Shower. The only thing that changes is the color.  Pink, Blue or Neutral.
Games at a baby Shower are quite important. Some examples are:

*Guess Mum's Tummy Size: (Materials- String or yarn and scissors) Have each woman pull the yarn to the size they believe would fit perfectly around the Mother-To-Be's center of her pregnant tummy. After everyone cuts their string, compare the results to the Mummy-To-Be's actual tummy. Give a prize to the woman who is the most close! This is a baby shower favorite.

*Guess the baby pictures: Ask for everyone's pictures prior to the baby shower. Have all the pictures in a collage and make lines for people to fill in who they think the babies are out of the girls at the baby shower. If most women don't know each other, just have the pictures of the mother, mother-in-law, sisters, and mommy-to-be. See how many people guess right. You can make copies of the baby picture collage to see how many can guess right!

*How Many Baby Items Can You Name: (Materials- pad of paper and pen for each woman). Have each woman write down as many baby products as they can name (bottle, blanket, pacifier, etc) within 5 minutes. Sure it is easy at the beginning, but towards the last few minutes, the women will start racking their brains for more :) Give a prize to the woman who gets the most baby products named!
