It is northern lights theme from Tera Callihan's video. I think that it is one of my favorite video's to watch to do northern light. She makes it so easy to follow. I did 2 things for the challenge. I made a card and a bookmark.
I did 2 because when I did the first one a big blog of white paint came down an messed it all up. But I saved part of it and made a bookmark out of it.
