Introduction: Emmet Lego Figure Costume From LEGO MOVIE

Picture of Emmet Lego Figure Costume From LEGO MOVIE

My son wanted to be Emmet from LEGO MOVIE for Halloween so I looked all over for the costume @ every retailer imaginable, after I had run out of options I decided that I would try to make his costume at home. The head and hair are just a sheet of dense foam. I cut out many of the needed diameter and glued them all together. after that had died I used a coarse wood file to start shaping the foam to my desired shape. I then coated it in resin and painted it. The whole body is nothing more than precisely cut junk cardboard scraps taped together and covered in resin.

Step 1: Measurements of the Person That Is Going to Be Wearing It Are "key"

First thing you need to do is get some measurements. You want the costume to fit the person you are building it for. You can't expect to build it and just hope they can fit in to it. Get measurements of head, shoulders, chest, mid section, waist, legs, feet, etc.. I took every measurement I made and added one inch to it. That way the costume would fit "snug". I found a flat piece off cardboard and started drawing out my measurements. I decided how wide the waist needed to be to look the most "lego like", then based everything from the waist down off of those measurements. Having a lego figure with you will really help with this step. I drew it out with tabs so that it didn't have gaps on the corners after I cut it out and folded the cardboard.

Step 2: Drawing Out and Cutting Your Foam for the Head.

I got a dense sheet of foam to use for the head and hair. I figured out my measurements by comparing the little lego guys proportions in my hand vs. the mid section that I had just drawn out on the cardboard. To make the circles on the foam you can either use a protractor or the ol' nail on one end of a string and marker on the other end. Depending on your thickness of foam you will need to determine how many circles you will have to cut out to reach your desired height. keep in mind that one of the circles you need to cut out are for the neck so it will be about 2 inches narrower than the others but should be figured in to your overall height. Use either a thin steak knife or an old hack saw blade wrapped in tape like I did to cut out the circles. Make sure to keep your blade squared up with your sheet of foam while cutting out the circles so your circles don't end up having angled edges.

Step 3: Gluing the Circles of Foam Together.

To glue the circles together I found it best to use either wood glue or Loctite G02 Glue (which dries like rubberish foam) First choice would be wood glue though. When you glue the circles together you should line them up as flush as possible and keep the glue back away from the edges about half an inch. Also keep in mind that there will be a head in the middle of this so glue where the head will be is a waste of glue. After glueing them all together including the neck, I flipped them over upside down and found the heaviest object to sit on top of them till they dried. In my case I used a car battery for a weight.

Step 4: After a Day or So Its Time to Shape and Hollow Out the Head

Using a coarse file and 80 grit sand paper I smoothed up the head and curved the edges to make it look more like a lego head. after you're done with shaping its time to add the lego tab to the top of the head. Again I figured out my measurement by comparing the foam head to an actual lego head. After glueing the lego tab on top of the head you'll need to let it dry the same way you did the rest of the head. When it's dry you'll just need to slightly sand and roll the edges of the tab to make it look right. After that I drew my sons head measurements on the bottom of the neck with a marker and started carving out the foam until I reached my desired size. make sure to carve out a little extra for their nose to sit comfortably.

Step 5: Test Fitting the Head and Chest.

Just try it on at this point and make sure it all fits like it should. Now is the time to make changes if needed.

Step 6: Drawing Out, Cutting, and Building the Rest of the Body

To make the legs and crotch (which holds the legs) I used cardboard and a cardboard concrete form for the radius at the top of the legs. Tape it all together and test fit the costume again to make sure they can move around freely in it.

Step 7: Making the Hair.

I forgot to take pictures of this but what I did was set the head out and pretty much made half moon pieces of foam that fit around the head all the way to the top then cut out the pieces like doughnuts to go around the head for the bangs and top of hair then topped it off with a smaller circle. I glued it all together and held it together with toothpicks and wedges till it dried. I then shaped it with my file and sand paper.

Step 8: Covering Everything With Primer.

After everything was were I wanted it I covered all of it in fiberglass resin to give it a rock hard shell then coated all of it with very heavy coats of primer.

Step 9: Painting...

I then very heavily coated everything it's desired color using spray paint. Notice the AMAZING thick shiny finish. You get that from taking your time and applying many many even coats.

Step 10: Detail!!!

The white and blue of the shirt are spray paint that I taped off and sprayed. The reflective stripes are glitter duct tape that I found in the arts and crafts section of a local store. All of the black is Sharpie marker (make sure to get a bunch of brand new markers because they crap out pretty quickly on here) The red and black on the face are Sharpie marker and the white teeth was done with spray paint.

Step 11: You'll Need a Way to See So Determine Where Your Eyes Will Be and Cut It Out With the Saw Blade. in My Case the Look Out Is the Mouth.

Step 12: Enjoy!

Hello how so you apply the fiberglass resin? Could you apply this to paper/cardboard items to stiffen it? Is this water resistant?

Ebeams2tja (author)2016-08-26

Did you keep the tape on the whole time, or did you take it off? Also, did you use fiberglass resin right ontop of the cardboard? Thank you, trying to make this for my son for Halloween.

MascotS made it! (author)2016-04-26

very good, i feel make it so easy .

snizbatch made it! (author)2016-02-16

Thanks for the guidance! It wasn't easy, and it was a bit awkward for him to wear; but it was a real hit!

HenryB24 (author)2015-10-26

You put fiberglass resin directly on the foam? Won't that eat through the foam?

Emerie1850 (author)2015-10-22

When you coated the head with fiberglass resin did you just brush it directly on the foam or did you lay a cloth on the foam and then brushed the fiberglass resin over it? If so does it have to be a specific type of cloth?

Blaze03 (author)2015-10-22

the belt is pretty much a T shape that matches the curve of the top of the legs. The legs are actually worn by suspenders which carry the entire weight of the costume in order to keep the legs from dragging the ground. You can contact me via email @ then I can easily send pictures in

kkat (author)2015-10-21

I'm having a hard time figuring out the crotch and belt. Could you explain or post pictures of how it all connects?

GregF13 (author)2015-09-30

I'm trying to make this but having a hard time sourcing the foam. Any resources online or a foam type/name I can search for?

eblair5 (author)GregF132015-10-07

You can get the foam in sheets at home depot in the flooring section where the carpet padding is...its polyurethane foam

GregF13 (author)eblair52015-10-09

Thanks. When you used the fiberglass resin, did you use the cloth to reinforce the fiberglass or just the resin?

Blaze03 (author)GregF132015-10-09

There is no fiberglass on this costume. I used cloth in place of the fiberglass for a smoother finish

ErinC16 (author)Blaze032015-10-11

Fiberglass cloth or fabric cloth?

GregF15 (author)Blaze032015-10-09

Sorry for all the questions, its my first time working with resin. So rather than using fiberglass in the resin, I should use something like 3M 499 Fiberglass Cloth with the resin?

kaw487 (author)2015-10-10

What specific brand and type of primer was used for the foam and cardboard before painting? Did it help smooth out any indentations in the foam? Thanks!

1truedrum (author)2014-11-16

You mentioned that his vision is through the mouth? Looking at the final photos I see a painted mouth with teeth and tongue. I cannot see any screening used or a cutout in the mouth. Would have like to seen a video of this costume in motion. The legs, hips and torso are seamless which would make leg movement difficult.

Blaze03 (author)1truedrum2014-11-16

Herei just took this "seamless" photo just for you. Now which parts are seamless???

AleashaB1 (author)Blaze032015-10-06

Hello, I was wondering if you can maybe send detailed leg info if possible. I'm having a hard time seeing that photo up close.

Blaze03 (author)1truedrum2014-11-16

Here's a few from two different Halloween contests. I didn't think to take video.

Blaze03 (author)1truedrum2014-11-16

here's a better photo of the mouth

ErinC16 (author)2015-10-04

What kind of fiberglass resin did you use? This is amazing. I am doing Batman and the joker.

JessicaJ15 (author)2015-10-03

I just started my son's costume, but trying to figure out how u did the legs...

DeziraeP (author)2015-09-27

How long did this take you? This is absolutely amazing!! Great work!

dkorford (author)2015-09-19


Blaze03 (author)dkorford2015-09-19

SUPER DAD not mom, and thank you!

HollieS3 (author)2015-09-13

This is amazing! You pretty much won the father of the year award with this. Very creative and dedicated.

MarkP47 (author)2015-09-12

what an absolutely fantastic outfit. Could you please tell us what type of foam you used to construct the head? Is it the same from that people use for flower arranging?

Blaze03 (author)MarkP472015-09-12

It is the same kind of foam they use in flower arrangement but purchased in a 4x8 sheet at the fiberglass facility I work@. People use it for forming molds.

PopolDal (author)2015-07-30

What kind of foam exactly did you use for the head?

PS: Very nice job!

kgirl5523 (author)2015-01-03

Wow...that is amazing at first I thought it was a real Lego man!:D

TheFrankTurk (author)2014-11-25

Emmet -- I just wanted to tell you that if I had been a judge in the Heroes/Villains contest, you would have gotten my vote for first prize. This build looks great, the instructions are easy to follow, anyone can do it, and I would wear one.

Blaze03 (author)TheFrankTurk2014-11-25

Thank you very much! That means a lot to us! We were really disappointed in the results as well. Maybe next year...

joanne.zomaya (author)2014-11-20

love the costume! just wondering if you could provide some instruction on how you created the hands?

Blaze03 (author)joanne.zomaya2014-11-21

I apologize! I didn't realize that I hadn't put the hands in my instructions. the grey rod inside is a plastic fitting I found at the hardware store that fit snug inside the pvc. I used that same loctite glue to glue everything together and used silicone to make a smooth edge between the hands and wrist before painting.

1truedrum (author)2014-11-16

Thanks. Seamless meaning there is no visible gap while standing still. The human leg naturally bends which would lift the Lego leg up and forward causing it to crash into the hip and torso. Just trying to understand your mechanics.

Blaze03 (author)1truedrum2014-11-16

Oh okay. Well it's identical to the way a lego figure moves. The legs only move at the hip but the legs are hooked to suspenders which makes them float about 3/4 of an inch off of the ground so that they don't drag. the top of the legs are cardboard cylindrical concrete forms which allow the legs to pivot much like a lego figure does. I could have given him knee joints to make walking much easier but since he was a lego I thought it was better suited to move the same as a lego

Duckism (author)2014-10-30

your son is very lucky to have a father like you whos willing and have the kill to create such perfect costume for him.

Blaze03 (author)Duckism2014-11-09

He won the costume contest here in the town we live in, but I didn't get to share Halloween with them because I had a stroke the morning before Halloween. I was in the hospital for ten days. It was great news to hear that he had won though! Thanks for all of your positive feedback!

babylake (author)2014-11-03

every thing about it is awsome

Sal Pic (author)2014-10-31

How does he move his legs?

Blaze03 (author)Sal Pic2014-10-31

just like a lego man moves his legs

Sal Pic (author)Blaze032014-11-03

Ok so the legs and crotch aren't fixed? It was hard for me to tell from the pictures. I take it he had no trouble getting around on Friday huh?

Blaze03 (author)Sal Pic2014-11-03

No the legs and crotch are separate and the crotch has bolts that attach it to the upper body. The legs have staps that go over his shoulders underneath it all do that the legs are just slightly suspended so that they don't drag the ground

Sal Pic (author)Blaze032014-11-03

You did such a good job you can't even tell they're separate pieces!

PhilTee (author)2014-11-01

Outstanding! The hair in particular is BRILLIANT!

jjones0013 (author)2014-10-31

Amazing costume! The one thing I would ask for is more detail in the steps and pictures. Such a great job - I would love to try to put that together for my boy.

brian5003 (author)2014-10-31

Thats awesome! I have to make sure my kids don't see this, they will want me to build them these every year :) . Nice work. Are there eye holes? Can he see?

Blaze03 (author)brian50032014-10-31

you look though the mouth.
