Chantrel made a pair of Sais for a costume.
“This was my first try at making any sort of prop. I made these for a convention I’m going to. The base is coat hangers and duct tape and then I covered them top to bottom in InstaMorph for added shape, stability, and paintability! This stuff is seriously amazing. The picture with the mask is one of the sais before it was painted (the only picture I snagged of them)”
As you can see from the photos, the paint job turned out really well. The base of each mock weapon was wrapped in duct/electrical tape for added grip and aesthetics.
Maybe the costume is Raphael from the Teenage Mutant Ninja Turtles? Probably not, but one can hope (and age themselves by hoping).
