Ghost on the door

We started to decorate.  So the other day we painted ghost on the front door.  I think it turned out pretty cute.  Although Nolan has messed one of them up already.  

The recipe for window paint is

1 cup baby soap, or clear dishwashing soap

1/2 cup cornstarch
food coloring.

I just searched online for this.  I think you can also do paint and add clear dish washing soap to it.
