It started out as the spot where I used to nurse my boys at the end of the day when they were infants—and quickly transformed into our favorite reading corner. That was before my older son moved from his crib into a bed large enough for me to crawl into with him. Yesterday, with pillows as a barricade, the Nook became a fortress, where the “the good guys” shielded themselves from enemy fire. Last week it was a mini sub one day, and a space ship in an asteroid field the next. The Zelig of living spaces really only requires a corner, a decent light source, and lots of pillows. You can posh it up if you’d like: We had a fitted, down-filled cover made for a standard full size mattress with pillows to match by a local seamstress. My handy husband even faked a couch base over the bed frame by taking scrap wood and upholstering it with a piece of foam and a staple gun.
