I love pop ups. Pop Up books, cards, art. Any popup! It is so fun to open! This was a Silhouette file I got. The silhouette designer didn't give any help to do more than cut it. I cut it out of black and a colored paper. I removed the piano from the colored paper and layered it over the black layer. I cut the small keyboard out of white as well. Then, I took two pieces of purple cardstock and layered them as the front and back, sandwiching the black layer in the middle.
It is decorated with peel-offs, washi tape, and embossed paper.
