Armed with winged black eyeliner and hot pink lipstick, Lauren Conrad showed us exactly how to throw a party when we visited her at the Pinterest offices. The style, beauty, and party planning guru was prepping for the release of her newest book, Celebrate, and invited us to see exactly how celebrating is done.

According to our friends at Pinterest, the Laguna Beach star used Pinterest for inspiration when writing Celebrate, and she even used secret boards to help plan the book.

“Everyone in my life knows what a Pinterest fanatic I am…so it only seemed fitting that I launch a few new Pinterest boards in honor of my party-planning book,” the reality star turned author wrote in a blog post. “My four newest Pinterest boards are meant to give you a first glance at some of the fun party planning topics I tackle in Celebrate: DIY Party Décor, Party Eats and Treats, Think Pink Birthday Party, and Celebratory Cocktails.”

Browse through our slideshow to find out exactly what LC taught us about entertaining a crowd!

Always have a table decorated for impromptu photos of your guests crafts, cocktails, or even plates of delicious food.

Flowers make a beautiful backdrop for photos, but activities involving flowers that your guests can take home are much more personal!

Learning how to make a bouquet is FUN, and it’s a skill you’ll never stop using (and LC is an expert!).

You can never have too many snacks! We absolutely loved Lauren’s Almond Joy and Cake Batter Popcorn. Get the recipe for both of these party treats here.

DIY crafts are a great way to engage your guests.

Always take time to interact with your guests…and join them in crafting awesome DIY wrapping paper.

Have a few props lying around so your guests can capture super customized photos of your party!

Make your own paper tablecloth to match the theme of your celebration. In this case Lauren made sure there were quite a few DIY table covers with #LCCelebrate to promote her new book.

Always decorate with flowers. And they don’t need to come in the form of a lavish bouquet! Simply styled blooms do the trick, too.

Last, but definitely not least, greet guests with your warmest smile. There’s no better way to make your guests feel like it’s time to party than to spread the right mood around!
