You may use any kind of paper to fold this origami butterfly. Here I am using the same color paper for both the front and the back sides. But you could use one side color only paper without any problem. Make sure the paper that you use is a square (all sides are equal and all the angles equal 90 degrees). The paper I am using here is 14cm x 14cm square one.
