A muse Studio has some really great die cuts in this catalog, and one that I am very excited about is the Butterfly Trio. They are the PERFECT card size. Just email me on the contact tab at the link above and I'll order them if you are interested!
I was able to create these cards super quickly! All three sizes included in the set are on the center card and the right and left card are created with the largest die cut. Actually the red butterfly is created by the negative space from cutting out the white A muse Studio Butterfly! How fun is that?
