Hey! I casted them out of resin from a master I made out of plastic. If you don’t mind scrolling down a bit, I have posts about how I made them here: http://ladys3.tumblr.com/tagged/black+widow
Thanks for the compliment! It was the first time I learned to work with resin and though mine don’t light up, I’m really excited about them. I chose not to light them up because her’s don’t light up in any posed photos, but if you go that route, I know people are using LED’s.
