Escher Butterflies

One of my favorite artists is M C Escher because he is very mathematical as well as artistic.  One of his works features butterflies that appear to fly off the paper.  I saw a card similar to mine
http://lezardsdecilou.canalblog.com/ and thought I needed to make something like it to honor Escher.  I stamped on a piece of Epic Day This and That Stampin' Up! designer paper.  But my trick was I used two butterflies to make this card.  As the butterflies approach the end of the paper I attached them with first one then two dimensionals.
