Making a corner bookmark is quite easy because all you need is a square piece of paper to make them. Once you have that in place, twist the rectangular piece to make a diamond. Then bring the bottom corner up to the top and make a neat fold at the bottom. Next, fold both pointy edges and bring them to the top. Finally, neatly crease and fold all sides. Making careful and neat creases will help you later on. Next open, and bring one flap down and bring the opposite flap over and tuck it under. Similarly, do it for the other corner. And that’s it; you have a basic corner bookmarker. You can always check out a few cool YouTube videos to get bookmark ideas.
