For the head piece I watched this great tutorial:
And I bought a twig wreath at Goodwill, which I tore apart. And almost all my leaves and flowers were from some awful Goodwill wedding centerpiece. haha
And for the dress I used this tutorial (except I added a zipper to mine):
The body of my dress was made from an old sheet, and the rest of the fabric/cord was from JoAnn's.
The makeup was done with many green/brown eyeshadows. And then I eyelash-glued all the leaves onto my face/body. They lasted almost the whole night. And the lashes are feathers!!!!
