Hello Puddin ~!

Ready to make your own epic Harley Quinn hammer? I am here to show you through the steps of making your own!

I am going to try to keep it as short and as easy as possible. Who wants a wall text anyways, when you just wanna get to crafting? You creative souls can most likely relate…
Let’s get to it!

Thick EVA foam and 3-4 mm EVA foam for the handle
Worbla (I used the original; Worbla’s finest art)
Broomstick / Or PVC pipe
Gesso for priming
Different acrylics
White Spray Paint
Red Spray Paint
Glue patrons
Brushes for painting
Masking tape
120 sanding paper

Heat gun
Glue gun

Time to start!

Step 1:

Cut out several layers of thick EVA foam to the desired width. I used about 10-12 layers to get the thickness I desired for the hammer head.
Glue them together with either contact glue or hot glue.
(Contact glue is stronger but remember to be in a ventilated place due to gasses coming from it. Since it’s winter I decided to use hot glue as I’m gonna cover it in Worbla anyways)
Also, attach a 3-4 mm EVA foam piece at the bottom of your broomstick / PVC pipe for the handle.

Step 2:


Carve your square hammer head into a roughly round shape. I drew a circle so I could kinda tell how far I could go with the blade. After you cut most of the unnecessary EVA off, you can start using a belt sander tool to get it even more round + smoother. Other kinds of sanders can also be used, but belt sanders are the best when you want to remove material.

Step 3:

Wall plaster!

Let’s cover some dents and gaps with wall plaster! This is so the thermoplastic does not take shape of imperfections. You can get many different wall plasters, but the lightweight ones are recommended. Be sure to let it dry 100% before you start sanding. If it is still wet, you might just sand chunks of it away and you’ll end up having to apply more. You can also apply some at the bottom of the handle to cover the gap.

Step 4

Time for Worbla!

Worbla is a thermoplastic which gets soft heated using a heat gun. Almost like gingerbread dough! (Do not eat it though, although it might seem tasty) One of the worbla sides may seem shinier, but it is no different from the other side at all.
(Be sure to place some baking paper or a silicone underlay underneath the worbla, that can handle the heat as the worbla gets sticky)
Heat the worbla up until it becomes soft. I cut out a piece for the middle part first, and simply rolled the worbla around the hammer head, then I applied the sides at the very end. Make sure you seal the edges well.
There are 3 diamond shapes diamonds on one side of the hammer head. I simply made double-layered worbla diamonds to make them pop even more.
Don’t forget to cover your handle with worbla as well!

Step 5:

Let’s get the Dremel ON!

I use this to sand the worbla smooth. Wherever you get bumps or edges you want to remove, use a dremel to remove them.
If there are deeper dents and such you can cover your worbla piece in some wall plaster as well before we get to priming.
I also added some battle damage and carved some wood-like textures and the smiley face on one side of the hammer.
Make sure to dremel/drill out a hole at the bottom of the hammer head where you can attach your handle.

Step 6:

Priming + Sanding time!

This is most likely the most boring part of the whole process, but also very important. I applied around 6-7 even thick layers of Gesso. Make sure each layer dries 100% because we are gonna stand it down by hand after the last layer. I recommend 120 grit sanding paper for this. You’ve got to apply some pressure when sanding and it might seem a bit hopeless at times, but you just gotta keep going until it is entirely smooth. I have tried other priming sprays and such and they just crack after a few uses. Gesso has been the most long-lasting primer and I am super happy with it.

Step 7:


Time to start detailing with some paint! This is the best part in my opinion.
Make sure you line up where which areas are gonna be wood and which areas are going to be black/white and so before you start painting.
I started with the wooden edges of the hammer head first. I started with a mustardy base colour and faded it out towards the edges with a more brown-ish color and then some black. Make sure you get a good fade on it to make it look more realistic. Also, add some wooden textures near the end and keep on detailing until you get a look you are happy with.

Step 8:

Spray Paint!

The middle part of the hammer head is more smooth and clean so I decided to go with spray paint for these parts. I use masking tape to cover up my already painted parts and start making the pattern I want to spray paint with the masking tape. This includes the black stripes, the middle white part and the red diamonds.

Make sure each part dry 100% before masking of any other spray-painted parts, because if you don’t it might take the shape of the masking paint, or even rip it off! Refer to the drying times on the spray can – it can take up to 24 hours!

Spray paint your handle blue and the bottom part black. I also used clear high gloss spray paint on the handle.

TIP: The spray paint needs to dry completely before applying masking tape over previous sprayed parts

Step 9 :

Final details!

Go over your pieces and add some more shading to the handle + the text and you should be done! I hope this tutorial was useful to you to get your HARLEY ON!

The text around the hammer says:

Thick text = blue
normal = red

You’re so funny. 
You’re killing me! Or am I killing you? Hahaha! Wanna play?
