Hiya,

So I'll be officially cosplaying for the very first time next year at MegaCon in Orlando Florida.
I'm going as Lady Loki.
I'm not worried about the clothing.
I'm worried about the horned headpiece.

It needs to be light enough to be on me all day.

Any suggestions? I'd appreciate them

Depends on what you're able to work with! I've got a ton of ideas, though.. :)

Use http://www.dickblick.com/products/amaco-wireform-mesh/ or something similar for the general shape of the horns, then coat them with paper mache, plaster rigid wrap cloth, Wonderflex, casting plastic that you can brush on, or fiberglass. Those would be really lightweight, but I'd be worried about the horns getting dented in transit or if you tap a doorway as you're walking around.

Use insulation foam - it comes in 4'x8' 1/2" thick sheets at most home repair stores, usually in pink or blue. It's really easy to cut and shape with knives and sandpaper, then it can be coated with fiberglass or the other stuff from above. They'll be tougher to dent than the hollow wire shape ones, but working with insulation foam can get quite messy...

For the center part of the headpiece, you might want a bit more support than on the horns, so I'd do a couple of layers of whatever material you used for the horns.

Hm, hopefully something in there made sense.. also, if you have access to other tools or materials, I have several more ideas.

I'm pretty willing to buy any sort of materials you may have ideas for as long as it can turn out:

A) Pretty Sturdy.
B) Good Looking

All the ideas you gave though were great I did find this online http://tonyloki.tumblr.com/post/33562833829/lady-loki-progress-diadem so that was some visual aid.

Hm, looks like they tried the blue insulation foam, but had it cast in polyurethane resin later (and said it was heavy, so it was probably a solid cast). If you go with a solid cast like that, I'd definitely suggest a much stronger centerpoint, and using screws to attach the horns so you can pull them off for transport.

If you make your own mold, you're probably looking at about $30-50 in silicone, plus casting materials later. I'd say try contacting this person and seeing if they can do a slush/hollow cast for you, or if they can add in some filler material to make the horns lighter and cheaper overall.

If you give me the sizes for the horns (or better yet, a 3D model), I can run them off on a CNC for you out of foam, and send them raw or coat them in fiberglass first. It's how I'd do things, since it's the best balance of cost/strength that I can think of so far. If you were doing more than the two, a mold would be better, but the CNC will let us get the two horns exactly the same, at least.

So how does the CNC work. Could I render a 3D model in the computer and save a digital file for you?

Doesn't need a rendering of the 3D model, just the source 3D model in something like Max, Maya, Blender, OBJ, or others, and how big you want to make it. The robot will take care of moving a carving head around to cut out the shape you provide, and can make any number of copies at different sizes (or mirrored versions if needed).

I'll PM you my email so we can talk further about this, it's kind of getting esoteric for general forum stuffs.
