How to hold up a textbook with a piece paper?

Ok so I have a project for tech. I have to find a way to hold up a textbook with just one piece of computer paper. The only things I can use is scissors, a ruler, and a pencil. I don't know what to do. Do you know any good shapes or techniques?How to hold up a textbook with a piece paper?
fold it like a fan in one inch folds sideways(the long way) then set book on itHow to hold up a textbook with a piece paper?
cut the paper into multiple rectangles, make these into a cylinder by rolling the paper. make them one inch diameter. make them the same height. place the circles under the textbook, one in each corner and any extras in the middle areaHow to hold up a textbook with a piece paper?
Try cutting the sheet of paper into 3 equal height strips, then fold each of the strips lengthwise, rolling the strips tightly into a spiral. Position 2 of the spirals upright near the book binding (one on each side supporting the pages) and the third maybe halfway to the book's corner. It requires some good placement of the spirals to keep the book balanced for long- if the book starts to open up, it will fall over. Maybe use a new, stiff textbook ?
