Can anyone give any suggestions on how to make Judal's bracelets and necklace? (The Labyrinth of Magic or Magi) I want to make them easy to slip on and off but also accurate to the character. any suggestions?
Really late...
I'm not familiar with the character and how the bracets seem to move on his arms or what the most "canon" interpretation would be, but doing a quick search, I see three main ways that his bracelets are depicted in artwork, and whichever way you like the best or think you can do should be the one you choose.
1. A single piece of relatively flat, slightly textured metal
2. Something akin to plate armor, where it is multiple flat pieces all attatched together
3. Multiple round bracelets
I think that multiple bracelets would be the easiest way -- get a whole bunch of gold bracelets, or get a whole bunch of not-gold bracelets and spraypaint them all a uniform gold.
For option 2, look into plat armor tutorials. you may be able to accomplish this with some sort of foil or coloring method over craft, or you might be able to join together actual sheets of metal.
For option 1, you can either do metal and do some sort of repousse technique or otherwise add texture to it, or use a moldable non-metal material fitted to your arm and given texture (heated craft foam? the lines would be easy enough to inscribe)
For getting it on and off, unless it is quite flexible, I wouldn't use velcro, since otherwise it would need two pieces and unsightly seams and such (I used this method for armor for Lady Eruca, and it didn't work out as well as I'd hoped). You might be able to do a hinged side and some sort of clasp, but since a single piece would be rather large, I wouldn't attempt it, since that method seems to be used most on bangles and cuffs of no more than an inch or two wide. For something like plain craft foam (or with something just as flexible attached to it), velcro would probably work, since it would encircle your entire arm.
For something stiffer, I would use the method that a lot of actual bangles and cuffs use, which is to leave an opening on one side, so the arm can be turned sideways and slipped through. If you go with a lot of bracelets instead of a single piece, those can just be slipped on/off individually.
I would personally go with either the plate armor style or the multiple bangles style, just aesthetically...though, I've seen quite a few cosplays who do multiple bangles that are really thick, and it looks awkward, so you'll have to be sure that the proprotions are correct.
Hope that helps some. I know I didn't give you really any concrete answers, but it's a starting place.

... I think I posted this in the right forum? >.<
So I'm sewing a Female Roxas cosplay this year based on Roxas' casual clothes from the beginning of KH2, and I think I've figured out how to do mostly everything. Except for those darn checkers on Roxas' jacket.
I can't seem to find any good checkered ribbon or fabric that I could just sew on. For now my best idea is to cut a bunch of little black squares and sew/glue them on, but that is going to take forever.
Any other suggestions?
The most realistic-looking Roxas cosplay I can find on google tends to have the squares painted/screenprinted/glued(?) on, but if you are looking for something fast and easy to do yourself, that might not be an option. After a quick search, it seems as it ribbon with black and white stripes running the width instead of the length is quite impossible to find, as well.
Though, I found some black and white checkered elastic that comes in
1.5" and
1" sizes. It's elastic, not ribbon, so you'd have to be -really- careful when sewing to not stretch it, and it may look slightly strange once it is sewn, but it's an option if you can't find anything else.
Hope that helps!
