String voodoo doll costume?

I want to make a string voo doo doll costume for my daughter. I was going to make a paper mache head using a beach ball and cover it in rope but was worried about it being to heavy and how I would keep it from falling off . The cut out mouth would be where she looks out and then I would felton some eyes. I was going to attach ropes from her shirt and from her skirt and then fasten around the wrists and the ankles where the ropes would fray out like how a string voo doo doll looks like. I was curious of anyones input or thoughts/suggestions...thanks! I guess I need to create a couple of large pins to stick out too....so who is creative out there and can help me out! THANKS!!!!!!!!!! :)
