I think half the reason I wanted to make a Melisandre cosplay was to make her necklace. Once my friend Loren of the Costumer's Closet--who's done a lot of interesting work with props--suggested that the necklace light up, I knew I had to make it work. I found a few other necklaces online that lit up, but none of the ideas quite worked for my necklace, so I had to come up with my own way of doing it. This is an entirely new area for me! I know nothing about electronics--especially making them so small!
And about the post title--clearly, my subconscious was at work. I didn't really mean to make the reference, but since I do know nothing about this, it was a logical title, which obviously needed to be kept. More details about my trials and false starts at the bottom of this post.
