I decided to make a fort kit for my nephew and I was surprised how big of a hit it was!
(I know--I shouldn't be surprised, right?)
I meant to take a picture of all the stuff inside, but basically I found 2 sheets at a thrift store and sewed loops on all corners using fabric from an old t-shirt via instructions found here, added rope-suction cups-clips and a flashlight to a pillowcase/turned bag, and then made a cute tag with the description.
It kept the kids occupied for hours. Plus it's portable so it can go anywhere. They used it at the hotel room, outside, and I especially loved this little set-up at Grandma's house via the Christmas tree!
