I've been using the kit Trick Or Treat by Scraps of Ellay to create our Halloween layouts.
There are so many cut elements of kids in costumes. My son had been asking me to be a witch so I scapped that story so I wouldn't forget it years to come. And I couldn't pass up creating a layout with him fast asleep at the dinner after trick or treating. Now I just have to make a few pages in between ;-)
