I've been reading up on this newfangled Wonderflex and its friend Friendly Plastic.
I've been searching for something to make, at the very least, the calf armour for Gwendolyn, and potentially any and all armour for Oswald, if my boyfriend decides to go as him. Both are from Odin Sphere:
After reading the FAQs and tutorials for using Wonderflex and Friendly Plastic, I feel confident enough that this could be a good solution for making armour and maybe even weapons. I am going to order a small sheet of Wonderflex and a small container of Friendly Plastic to experiment with.
I am also going to pick up some Bondo, because (1) I have never used it before, heard some mixed opinions, and want to see what it can do, and (2) I wouldn't use gesso as suggested in the Wonderflex FAQ because there is no way that will not come off in chunks.
Once I get the materials and play around with them, I'll post my results with photos.
