Anoka Quilter, Owlie, I got the pattern for the Skeleton out of American Patchwork and Quilting October 2012. But, if you google skeleton coloring pages, you could probably come up with something similar for free. The block is 12 1/2 x 15 1/2".
The Witch, I got off of google Halloween images/coloring pages. (I just freehanded that one.) It might of been 2 images that I combined. I can't remember. I don't have a printer.
And Frankenstien is NOT my original design. I got the image off of Pinterest. I also freehand drew that one.
