Help!?
What can we use instead of a large cardboard box if we can't find one?
If you don't have a large cardboard box, drape a blanket over chairs, use a play tent or a laundry basket turned on its side to make the main room and then follow the step to arrange cushions and a blanket inside.
The taped tunnel keeps falling apart and the doorway is jagged—how do we fix that?
Have an adult smooth or trim the doorway, pad any sharp edges with extra tape, and reinforce the taped connection between boxes with strong duct or packing tape plus an internal cardboard brace for stability.
How can we adapt this secret space for different ages?
For toddlers, make a smaller supervised hideout using a blanket over chairs with soft cushions and an adult cutting the doorway, while older kids can tape several boxes into a longer tunnel, decorate with markers, add a folded map and flashlight, and include books to read inside.
How can we extend or personalize the secret space after it's built?
Personalize it by painting or adding stickers to the outside walls, attaching battery LED string lights and a fabric curtain for the doorway, making a secret pocket for the folded map, and placing the flashlight and favorite books inside to create stories to share on DIY.org.
