You need a rectangular scrap sheet, a flat surface and something to mark with. Choose a name or made-up word for the front. Put the sheet flat with its two short edges at the left and right. Bring the right short edge over to meet the left short edge. Press the folded edge. Open the sheet a little, like a book with two covers. Turn it so the folded edge is at the top and both open short edges rest on the surface. Mark the chosen name on one outward-facing side. You can choose the name before laying out the sheet or lay out the sheet before choosing the name. The edges must meet before you press this crease. If the stand slips, change the opening a little or ask an adult to hold it while you mark. Nobody has to fold or test one today.
