Freaky grandson

I made a new banner for this blog. Inside the left frame is a photo of my grandson dressed as The Scream. His favorite Halloween costume. You've heard of kids wanted to be the sheet ghost year after year--OK I'm aging myself--well, this guy loves to be The Scream. He'll be on the blog until Halloween. He's quite thrilled. He found the Halloween Peeps I bought. Ate them quite heartily---yikes! I would love to learn how to make marshmallows. Anyone out there who can help me?
