... Make a living room tent!
When I was a kid, we loved to make a big blanket tent in our bedroom. It helped that we had a bunk bed. Now my little girl loves to have a little place all to herself in our living/dining room:
Ok so basically it's a blanket over a dining table, but to her it's a secret hideout!
If you haven't made a blanket tent in a few decades, get to it!
