First off, i really like some of her ideas and have used a few and gotten tons of compliments.

But, i've never seen a tree that matches. If i were you, i would just make my own stencil. You could just draw it out. That way it is the exact look you would like.

Not as creepy, but free:

Make a Creepy Halloween Tree

I'd find a pic you like and try using either a projector or just freehand it to get the silhouette the way you want it if you don't want to purchase one of the patterns...

Thank you for those. I finally decided to just find a picture of a creepy tree and draw one in Illustrator. I enlarged it and printed it to the 6 feet I needed. Thanks guys!
