Below, we will present a method of making a cheat sheet that can fit a lot, while keeping the dimensions small.

What will you need?

• A4 sheet
• scissors
• tape
• 2 matches
• rubber band or string

How to do it?

Cut out strips of paper with a width no greater than the length of the match. Glue the cut strips together to form one long one. Cover them (the more of them, the greater the area of the tie rod) with text, and stick a match on each end. Roll up the prepared cheat sheet and tie it with an elastic band (so that it does not „break”). By turning the matches, we have access to the entire text.
