Here are few steps to made Poison Ivy Plant for Batman Miniature Game with green stuff :) I was planning to use it as a base for Poison Ivy but if needed it can work as separate model.
To check full process please check full post :)
step1 (cork base + some wires)
step4 (here is example how 28mm model would fit into this Plant base :) )
step 5 (more small items.. roses, spikes spikes and more spikes :)
Hope you like it !
