Fort building was so much fun! We used Daddy's old climbing rope, tied between two trees, and some woolen blankets to pitch the tent...Boo 2 couldn't quite reach to get the blankets over the rope, but chanted, "reach, reach, reach, Mommy, can you help me reach."
We had a blast crawling in and out, and I loved that she'd run out, then catch me with a big hug. There was a game of hide and seek, chase the dog, and we even had "lunch (grass) and nap. Fantastic fun! 
When it came time to put it away Daddy's rope became a wonderful hang and swing. I left it up for play in the garden today.
