I do this with drawing, but it seems that it will work with writing too! This is for writer’s block, which many suffer.
So, what you do is have three columns. The first is an adjective (smelly, green, etc.) The second should be a verb with and ing: (singing, dancing, etc.) The third will be a noun (toothbrush, apple, shoe).
1. Sparkly Thinking House
2. Tiny Dancing Kite
3. Hairy Sleeping Mouse
And so on. You should have about sixteen or so.
Now, just think of three numbers. If I think, 3, 1, 2, then I will write about a Hairy Thinking Kite.
Be creative and have fun with it!
