Once I Crochet Tunisian Butterfly on Crochet Geek, I knew I had to make one. 
I did a few differences,  I used my the pattern stitch from the Tunisian and Crochet Scarf.
I also added the antenna which I though made it look more like a butterfly. To make the antenna I chained 12, 2 sc in the second chain from hook, and slip stitch in the remaining chains. Of course you make 2 and sew in the top of the butterfly.
