Warning Sign
Uh oh, danger ahead! Build a super sturdy warning sign for your toys or an imaginary monster. What are you warning people about?

Do the Stick Test
Try one tile. If it sticks, ask: is it stable, safe, clean, cool, and not important? If yes, proceed with mild chaos.
Safety: Avoid anything hot, sharp, electrical, fragile, dirty, unstable, or likely to annoy another adult.
