Wigs making/styling a Very Anime wig?

You might have good luck with making a yarn wig, or one out of soy fiber (i think its soy...), both are easy to style in spikes and more gravity defying ways, and are popular for more anime style wigs because of that. This youtuber has a fair few tutorials on how to make a yarn wig that you can use as a jumping off point.

 

What scale are you working with? Knowing that may help with mor relevand advice as some fibres work better in some scale than others and, as you've discovered with the acrylic, some fibres don't come in all lengths.

 

I second going with the "it's just cosplay in smaller scale" approach. Looking up tutorials, maybe of characters with equally full/gravity defying hairstyles, works best to learn the technique. Everything else is just more fiddly because of the scale, but otherwise it works the same.

 

definitely agree with trying similar tricks to cosplay! it worked out great for me when I did hair for playline dolls. I do reccomend volks' water wax for styling instead of hair sprays though!

 

Materials: Synthetic vs Natural
Synthetic fibers to help hold the shape, yarn or faux fur would probably be a good option if you want to go that way. Natural fibers like mohair do not have much of a sheen but are very puffy and soft. So it really depends on if you want a truly sculpted look vs a natural volume look.

Structure:
I would probably make the tiny pigtails clip-ons? Similar to old school Miku cosplay wigs. Other than that, the base of the wig is just a 2 tone middle part, with a slight zig-zag at the front. Depending on your material you could do a hot-water boil to help achieve the curl at the ends of the hair. There are surprising amount of really good cosplay wig tutorials on Deviantart and I would really recommend those.

TLDR: Yeah it will probably just be like building a cosplay wig.
