Rose Gold 18th Birthday Decorations

Rose Gold Confetti Balloons

Confetti balloons like these rose gold balloons pack are so cute. You can either place these around your party strategically, like on a stair rail or along the walls. 

Alternatively, you can blow up a bunch of these and have them floating around your party room!

If you’re doing an outdoor party, you can tie these to trees, hang them on the fence, or on the sides of picnic tables!! So cute.

I also love these “Happy Birthday” confetti balloons from Etsy!!

These 18 number balloons are so cute! Another perfect staple to your 18th birthday decorations.

You can use these as a backdrop for a photo booth or place them in a corner to set the tone of the room!

This party banner is the cutest! I love this rose gold version. This is such an easy decor piece to hang anywhere at your party.

Alternatively, you can choose this “Happy Birthday” tassel sign, which is also so cute! You could also get both these signs and hang them in different areas of your party.

With some balloons and props, this shimmer party backdrop wall will make the PERFECT photo backdrop. If you want all your guests to take pictures and post them from your party, this is such a great idea.

If you’re looking for something a little more affordable, you can opt for this rose gold tinsel party backdrop as a photo backdrop. Either way, you can pair these options with balloons and maybe even a neon sign to set the vibe.

There are two rose gold dinnerware options I found that I love. This first Happy Birthday tableware set from Amazon will serve 25 guests and it’s got everything you need in the prettiest shade of rose gold!

As I always say, I love decorating parties and events into the smallest details!

I LOVE decorating parties with custom drink tags! You can get them on my Etsy shop, with your age – 18, for the number drink tags.
