Really amazing result!! I need to find a primer like that cause it really makes the work look so clean and professional, and an air brush would be amazing too but ohh expensive 😂

Mitsuri's sword is soft and bendy according to the manga and also it's longer than her body. That looks so realistic tho-

[@ronnietheboywonder]

Maybe skip a few steps and make the foam longer for manga accuracy? 🤓

You can use a cheap yoga mattress as well, for extra durability. It's what we use to make foam practice swords in HEMA classes.

[@deafengineer]

I just so happened to have a build commission for a unrelated cosplay sword build that I was considering using some EVA foam for contact surfaces. This has so many great tips for makers just by showing products and how you're doing it. Thank you so much!

Aluminum. Respect to the man that discovered it.

[@rhin143]

I just randomly found you and i love it I get TO COSPLAY

[@Neophoia]

the only think I'd suggest about the supporting aluminium rod as a core, is check if conventions in the area you go to are ok with that. some countries do not allow props that have a metal core in them, for safety reasons. Great tutorial video, will probably use it as reference for props in the future.

How did she make the sheath/scabbard for the blade? Edit: She should totally do a hatsune miku cosplay tutorial! (Especially how to do her put the hair accessories on the wig so they look like their holding up the twintails without touching them. Also, her headphones as well as Rin and Len's and Luka's)

Back in the day there were no tutorials; and most people didint have easy access to all these materials. ♡ Ah evolution in motion. Nice to meet you and your channel btw.👋

[@alexr3454]

Thanks Lady!

[@Miyuyuki_1999]

Tip for anyone who does this: air spray the prop in a well ventilated area, or outside as some fumes may be toxic. I think this is common sense, but some people don’t know to do this! It’s just a friendly reminder. Stay safe and make some jaw dropping cosplays!

[@anita8742]

[@jack1701e]

This is a great tutorial, thank you! I'm completely new to this but want to try making a couple daggers/swords as a test for myself but was wondering how to do it (Think thicknesses of foam, the inner piece to keep it rigid, that stuff) and this video explained it! I think I can make my own props, they might be a bit janky, but it's a start!

[@trash-chancosplay631]

I made my tanjiro katana with 2 sheets of 3mm (i think) wood. They sell it at craft stores, i think it was 0.70€ per 1! I did basically everything the same, but withoutadding a rod, since the wood is pretty sturdy on its own. The paint job in this is so good thooo and I didnt know that if I heat up the foam it would get smooth again after sanding!! Thanks for that! 🌟🌟

[@Neptoon_dev]
