thanks for the reply....I did just that and found the source of my problem....

I left the top open to the sky....when viewed from below it sure did cast a outline.

So i added a burlap roof to block the light and the curtains....its pretty dark in there now and it will be hard to see an outline....

I will have better luck now hopefully the ribbon curtains wont interfere with the shooting....thats my only concern really...should be OK
