A double posting today. I just got thru reading the other blogs I look in on and Fallen Angel & Hidden Demons reminded me about RavensBlight 's web sight.
On it he has a Toy Shop full of free printable paper toys and scary masks to make.
If you are looking for a last minute costume mask and have a printer you are in luck. Even if you are not it is a great site to look in on.
