The 21 yards of cotton fabric I have in the sewing room. I can make clothes, sheets and shelter out of it. (I am making a set of quilts)
My current cross stitch project. Maybe I'd actually finish it.
Assuming no electricity I would swap the laptop for a box of books, chosen at random from my bookshelves.
We're going to a resort cabin for the next 5 days (no internet so it isn't paradise:D, but the food should be ok and the insects minimal). I'm bringing the laptop, my camera, clothes, some toys for the kids & a book. This sounds like hardly anything but somehow fills 2 suitcases, a dufflebag and 2 laptop cases (DH & I are each brining our own laptops) and takes up the entire back end of our car. DH complained we were taking as much stuff for 4 days as we take to FL for a week. That is because we are. There is a washer & dryer in FL so I pack 5ish days worth of stuff & do laundry there. We don't take toys to FL so they are taking up the space the the additional day or so worth of clothing would have taken. If we didn't need to take diapers & sippy cups we'd be almost one bag less.
