Lego Birthday Party Roundup – The Best of The Best!

I pulled some of my favorite ideas together a couple of weeks ago for Jack’s Lego birthday party, and we had a blast!

LEGO Party Invitations

The fun officially started when Jack’s unassembled Lego birthday invitations arrived at his guest’s houses. I got some great feedback from parents about how much fun the kids had putting the invitations together and even making new creations with them:

For the first time ever, I ordered a professional cake for a party. After Jack saw this cake on Pinterest, he asked about it all of the time:

About a month before Jack’s birthday I was introduced to Cake Me Tucson, who said she could make the cake for us! She did an amazing phenomenal job! Don’t you agree?

We decorated with red fabric tablecloths and green bubblewrap (to look like the green square Lego bases).

Jack’s picture was made with the iPhone Lego photo app:

 We kept the kids very busy during the party, which was wonderful because there were 15 guests! We played Speed Build, Pin The Shark On The Water, Lego Rescue, and colored our own Lego Minifigures!

Lego birthday Party Ideas

From the top:

1. Personalized Lego minifigures by Mini-Mizer, made into place cards with PicMonkey.

2. Custom Lego birthday party cake by Cake Me Tucson.

3. Pin The Shark On The Water, purchased from Amazon.

4. Lego Rescue Game – difficult for younger kids, but great fun for ages 7+.

5. Piñata! Jack’s favorite thing about every birthday is his piñata! Purchased from Target.

6. Party decorations: Custom Lego photo by Lego Photo App (free!); vase from Michael’s, filled with Jack’s Legos; red fabric from JoAnne’s; bubble wrap spray painted green; and favor bags. Bags included M&Ms, play dough, and a special birthday Minifigure. Lego man printables from Winks & Daisies.

7. Lego City party backdrop from Amazon.

I hope you had fun looking through this post and finding new ideas – I sure had a blast planning the party!

    This reminded me of my family’s pain expression “On a scale of 1 to stepping on a lego, how much does it hurt.” Speaking of which, I’m guessing that happened a lot at the party.

      It hurts SO bad, I know this! Matchbox cars hurt, too!

      Thankfully, the Legos were quite contained during the party!

    That is an amazing party! And that cake is incredible! Both my kids love Legos and it be great to plan their next party with this theme. I’ll keep your post in mind.

    Right on. I discover a little something totally new and challenging on websites I
    stumble upon on
    every day. It’s never a bad idea to engage the ideas and material of other writers and link to other sites.
