/cgl/ - Cosplay & EGL

Posting here since there's no handicraft thread- what do you gulls use for deco whip? Do you prefer jelly (silicone?) or other alt materials (modeling paste, heavy gel medium, etc)? My phone model has so few cute cases I figure I might as well make my own decode case. Would it even be cheaper to make my own and but single compinents/just enough for one case as opposed to buying one? I am so desperate for a non uggo case for a non apple phone...
