This super-popular toy has a very interesting history. It has been created in the 20th Century, in Denmark by Ole Kirk Christiansen, who then gradually developed the blocks to the plastic pieces we get nowadays at the shops. The name LEGO comes from the Danish phrase “leg godt” (“play well”).

LEGO had become a multinational company, their toys are available in almost every country in the world. They have even built LEGO-themed parks! The reason behind their success is the amazing creativity, and the great quality of their toys. As a parent in this generation, you have probably played with LEGO yourself.

With so many electronic devices around our kids all the time, it is important to have other options of interesting and entertaining things for the children to spend time on. The blocks are that type of option because they offer the players the opportunity to be creative, to think and to make a different construct at each play.

The new LEGO toys are even more creative and full of special pieces, which can be made into almost anything. In order to keep up with the ever-growing options in the market, LEGO has launched special editions of Star Wars themes blocks, as well as other special editions with famous themes that are attractive even for grown-ups.


Lego birthday set up

Alright, now that you have already picked the theme for the party, it’s time to start with the actual preparations. At this stage, you’ll want to have in mind how many people you’ll invite and how many will be coming so that you don’t buy too many things, or too less.

If you don’t know where to start, don’t worry! Organising a birthday party takes work, that’s why there are companies dedicated exclusively to this. Whatever your reason to prepare your children’s party yourself, we are here to help you.

In the following sections of this article, we’ll feature some of the most utilised Lego party supplies, including decorations and miscellaneous details which will give the party that wow statement. Again, these are some ideas that you can either follow or just get inspired by.

When it comes to a kid’s birthday party, there’s nothing that is absolutely necessary — besides the birthday cake. It is, however, important to think with a kid’s mind for a moment and try to remember how we used to be when we were children. Our little ones live in a world made of fantasy, something so simple as a colorful plastic figure well placed is enough to make them thrilled and happy.

As much as we recommend parents to have fantasy and imagination while pulling together a birthday party, we know you need to be practical and reasonable as well. That’s why we choose the most cost-efficient supply options we could find, so you can relax and choose what suits you best.


The standard Lego party supplies include balloons, a backdrop, scene setter, banners, the birthday cake table (if you choose to have one), a finger food table (perhaps), and a little more.

With the LEGO theme, you can either use the plain bricks and Minifigures, or you can elaborate more with a Star Wars LEGO, or a Super Mario LEGO Theme. With the LEGO Friends you have more than enough characters to choose for a girl’s birthday as well.

Here are some good ideas of how to bring your LEGO theme together starting with the item which can best represent your theme: the scene setter.

A scene-setter will give your kid’s birthday party a very customised style, no matter the venue you choose. This big, colourful and illustrated image has quite a special effect on the eyes of kids and adults.
