Searching through some old files on my computer and found this neat little photo collage.
We had to do a little engineering to figure out how to bring the ame-comi statue of Poison Ivy to life. It was really important to Kitsunebaby (the cosplayer) to have the vines as accurate as possible.
We sewed a sturdy backpack type rig out of wonderflex and nylon belt straps. Thick copper wires were weaved through the wonderflex back piece and secured down with more wonderflex. (The thin wonderflex is sewable, so we sewed the straps to the wonderflex for a sturdy secure bond).
The wires were bent to the right shape, and fingers armatures were created with aluminum wire and tape. Spray foam has trouble sticking to and expanding on non-porous objects, so we strung styrofoam balls and foil bits along the wire skeleton to give the foam something to grip to.
Then we sprayed away, until everything was covered in foam. Kitsunebaby then spent hours carving the bulbous mass into the creepy hand shaped vines Ivy has. She sculpted snake faces onto the bottom vines with model magic.
The vines were papermached to cover the holes, and painted green. For some extra interest and texture Kitsunebaby covered the vines in various types of dried moss and added some fabric leaves that matched her costume.
