With Halloween only 22 sleeps away (so my children tell me), they had some fun making haunted houses. I used this template found at Sarah Jane and there is a great tutorial on her blog if you need a guide:
My older two are getting to an age now where making up scary stories and getting a little bit spooked is fun. I assumed my youngest was not at that stage so I changed the template slightly to turn it into a castle for her.
Not to be outdone, she drew a spooky tree complete with face beside it.
