Since our recent trip to Vermont, SteelyKid has been obsessed with building blanket forts. These have mostly been in the living room, leading to a bit of angst at the end of the day when we need the blankets back. So i did a little reorganizing in the basement, and dug some sheets out of storage, allowing the construction of a longer-duration fort.
This covers the basement comprehensively enough that it's probably a little hard to appreciate how much stuff is inside. The critical thing, though, is that SteelyKid is satisfied with the result:
It looks like you have plenty of blankets and sheets for a really nice fort but for those who don't. Check out the local Goodwill, consignment shops, and charity supporting organization taking donations. Most of them get more sheets and blankets than they can even begin to deal with. When I checked they were always more than happy to part with huge bundles of bedding for a song.
Sheets are a key ingredient in any fort building but they also make raking up leaves, rake the leaves onto the sheet and use the sheet to carry a huge pile, protecting car seats after a pool/beach day, a ground cover for picnics or working under the car, capes for young superheroes (avoid jet engines) ... the uses are endless.
