My grandparents' house had a severe lack of toys, which is why my cousin (I'll call him Rocky) and I had to figure out... other ways to have fun.

There was a small space between the bedpost and the cupboard, just enough for the two of us to snuggle. Rocky would drape a blanket over it and secure it with cloth pins. He'd also keep a chair in front of it, as an entrance, of sorts. To get inside the little space, one would have to crawl under the chair.
I would decorate the space with a blanket as a carpet, pillows, small plastic potted plants and toys.

That was our tent.

We would stuff ourselves...
