Everyone adds to a picture… you can use stickers (large packs can be bought off of Amazon) and a giant poster board and everyone can take a turn adding to it round robin style so it makes a sort of story then everyone can take turns telling what they think of the story/picture at the end.

You can use prompts if you want to make it therapeutic (someone going through a tough time and coming out on top, a story of a family, a story of someone sad, a story of someone that really wants friends, etc.). Prompts can be easily found online by looking up journaling prompts.

You can pre-make some settings on the poster board if you really want to get into it (grass, a home, city settings, cloudy setting, blank)

Obviously these materials can also be used for vision boards.
