I had this Catwoman vinyl kit from Horizon in my stash for the longest time. I finally built and painted her. I used my own base, which was a regular wooden base that I covered with balsa wood strips, to make it look like she's making her stand in a warehouse.
The whip is a length of thin wire that comes with the kit. I made the handle end thicker with putty. You can see more pictures on my blog: Catwoman
