Hi javin,
I just came from pinterest too! I found this one 2012 Halloween blog hop page of free paper pieced patterns! There is twenty something on this page if you scroll down a little. Click on the last part of each listed and a pattern comes up. There are two that are not operable any more, but the rest all work. Very cute freebies!
