These papercut "Shadow Books" by Helen Friel are amazing! I love how the papercuts interact with each other, yet work as stand alone images too. I also like the idea of having papercut designs within a book format as it is something that is unexpected and I think the concept of a narrative within a book, using papercuts as a way to communicate is a really clever and innovative idea.
I also really like this poster design by Helen as the technique used really communicates the message.
