This is a great idea, just find some white lanterns and you can draw or stamp them with your favorite Halloween image. This would work really well with orange lanterns and black paint or black lanterns with white or orange paint. Really great for your party!
This is a great idea for decorations, you can spray chicken wire with black paint and wrap it around an old lamp shade or build your own and put it on a pedestal with a pumpkin or even a skull under it. Great for Halloween!
