At first I thought it'd be pretty easy, but it wasn't.
I tried many different techniques including clay, cardboard, and many other materials. I would've used craft foam, but anywhere I went, I never came upon any. I was at a loss since I couldn't get ahold of craft foam, so I thought to do something, it seemed, no one has thought to do.
Make the headpiece from paper mâché.
Step 1: Supplies
Since this is going to be a paper mâché headpiece you will need an adhesive. Now, you could buy the adhesive, or you could make it- which is what I did.
.glue(wood glue/white glue)
.a small bowl
.something to stir with
(This could also be done with water/milk, and flour. Also I won't be giving ratios considering the fact that I just winged it when making the adhesive.)
.sand paper (optional)
Step 2: Design
Personally I thought the headpiece looked somewhat like how Scarlet Witch's mask/headpiece looked like, so that is what I modeled parts of my headpiece from. Also I looked at MANY images of the actual horned crown Loki wore in the comic, as well as ones other people made. I would highly recommend this.
Start by sketching different shapes for the headpiece, and cutting them out. You can decide which shape looks best on you by holding the paper cut out up to your face in the mirror. This may take many tries before you get the right shape. (p.s. save your scraps. They can be used for later steps.)
Once you have your ieal shape of the headpiece place it on a piece of cardboard, big enough to fit it, and then some, trace, and cut it out.
Step 3: Crafting
You already have your cardboard base, so now you need paper strips, and adhesive.
Paper: most paper mâché works use news paper, but you don't necessarily have to use news paper. I used sketch paper, but it was newsprint material.
I just didn't have news paper at my disposal.
Step 4: Crafting (cont.)
Now that you have your paper strips, begin making your adhesive. (If you bought yours, then you can skip to the next step.)
To make the adhesive I mixed wood glue, and water in a small bowl, adding glue to thicken, and water to thin.
The adhesive shouldn't be so thin it runs as it is applied, but shouldn't be so thick it's like muck.
Step 5: Crafting (cont. 2)
Do this until you have a solid base. This is to insure the headpiece will be the right shape once dry.
Step 6: Crafting (cont. 3)
To get the 3D round shape of the horns I twisted small strips of paper into a sort of snake shape, and bent it to the horn shape. Now, you can begin step five.
Step 7: Crafting (cont. 4)
Step 8: Crafting (cont. 5)
Step 9: Crafting (cont. 6)
Step 10: Crafting (finish)
Sand down all sharp edges, or faults.
I would suggest using sand paper that is very fine grade.
I would recommend spray paint, but if you can't buy any, or just don't want to use aerosol use acrylic paint.
Go look awesome! Show off your work! After all you are Loki. ;)
Step 11: A.N.
I would like to sincerely apologize though because I originally planned to have pictures to accompany each step, but was unable to do so.
Nonetheless if you're reading this then that means you stuck around to read all the steps, and I would like to, once again, thank you for reading.
