If fabrics r us does fail you I found these two knits on fabrics.com.
You'd probably want the first one for the project you're doing. The only annoying thing is you'd have to darken every other stripe, which could be done with fabric markers. Also remember to get a stretch needle before trying to sew it or it will be an unholy mess.
Darkening every other stripe would be difficult, time-consuming, messy, and probably end up looking really cheesy.
Rinoa's rib knit is a wider rib than the one linked to here, so the "negative" part shows up more, making it look striped. It isn't; it's just how the "negative" part of a rib knit looks darker due to seeing the backside of the knit and it being in shadow, giving what you are seeing as a striped appearance. Any rib knit will give that effect naturally without having to be striped.
I need a bit of advice on a prop gun
I was planning on carving it out of probably a block of styrofoam, then sealing the foam with something and painting it. Since the gun is fairly flat, I was going to just use a sheet of foam so i just have to worry about an outline istead of carving the sides, as well, like I would if I used something like expanding insulation foam. I also need a rather large single sheet, since I don't want to have to somehow join together two pieces to create the entire length of the gun.
Would this even work? I'm not sure what to seal the foam with, or even if the rather porous foam I was looking at would be a good option. I was thinking of using gesso to seal the foam, but I'm afraid it will just sink into all the little holes and I'd need a -lot- to get a smooth coat. If that wouldn't work, what would? I was hoping that I could seal it (sand it, seal it again, etc.), apply my decorations (which will be a combination of cut pieces of craft foam glued on and hot glue directly applied to create the raised designs), and paint it, without having to cover it in something between the sealant and the decorations/paint. Would that work, and how sturdy would it be?
Also, I was planning on using a length of PVC pipe for the barrel (which goes all the way back, so I would just need to glue it into a channel on the top of the gun), but I don't know what kind of glue to use to attatch it (I guess that partly depends on how I seal the gun?) or if that will be too heavy, especially considering how lightweight the body of the gun could potentially be. Any tips there?
I was planning on doing something like this
, where piece 1 is the styrofoam body, piece 2 is the PVC pipe, piece 3 is an extra, decorative piece (though it might be good to make it structural somehow... any ideas?), and piece 4 is shaped craft foam that hides the junction (thank you, Atlus character designers, for giving her a decorative piece right there!).
