I went to the computer room, put Martha's video on and tried to follow the directions while Mac took pictures. What a joke! They must have been folding a sheet small enough to fit a baby's bed. We have a king-sized bed and the sheets are enormous. No matter how I tried I couldn't get them to fold like the video.
At the end Mac handed me a pair of scissors and I felt like cutting the darn thing up. Instead I kind of folded it, rolled it and stuffed it in the linen closet.
I admit it, I can't fold a fitted sheet.
