A while ago Meaghan mentioned to me that she wanted Harley's Cork gun, my response HELLS YEAH!
I'm not very good with props but I'm quite pleased with how it came out, the gun is a modified Nerf Maverick [link]
The gun is basically cut and pasted back together. I had originally put a bit more silver on it but I like it better with more black.
The wig is also cut and styled by me, its a long curly wig which I put up into pigtails X.x as well as cutting the bangs etc
EDIT: I was requested to put together a tutorial on the Harley Quinn cork gun, so I whipped something together. Feel free to comment/PM me with any questions. [link]
