SOLVED. Pre-1990s Collection of Children's Scary Stories including one called "Wolfgang"

[Joy]

I read this book sometime between 1988 and 1995, but I have no idea how old it was at the time. I don't remember where I got it either.

It was a collection of scary stories, with a larger story about a family telling each other those scary stories. I think they were all supposedly (within the family's universe, not in our universe) true. One was called "Wolfgang." It was about the mom going to stay with a family when she was a young girl, and the family had a boy who was a werewolf or something along those lines. There was an illustration of her with her hair in a braid.

The final story was made up by one of the kids. It was about a barbecue/cookout. All the kids went off to play or something, and never came back.

I think there were only a total of maybe five-ish stories.

Oh, I remember this was searched for: If You Want to Scare Yourself?
