lol thanks roxy, the white color is a mix of different of casting. i normally use the brush on plastic resin, but i feel experimenting and use pour in liquid plastic... turn out pretty good but freaking heavy D:.
right now im more into PVC plastic sheets, those are like wonderflex except they come in 3mm they bend when heated but not as much as wonderflex. the back of my MH are pvc. molding are usually for surface with curve and details. if it flat surface then i use foam + vinyl, if it need to be flexible then still use craft foam + paint lol. my friend recommended me a new product called apoxie sculpt. it way better then paperclay. tidus sword details are made from that
