Today, as it is Valentine's Day, I am going to teach you how to make this origami heart bookmark. I'm not that good with origami, so I learned to do this from a Pinterest tutorial, but I thought I'd share the basics anyway.
You'll need origami paper, which I do not have, so I tried it once with construction paper (which was sort of difficult because of the thickness), and then again with copy paper, which is still as big, but easily bendable, so I'd recommend that more. Either way, you'll need the paper to be a square, so I folded one corner across the paper, until two sides were matched up, then cut off the excess.
To start, fold the square diagonally, then unfold it and refold it diagonally the other way. From there, fold the top point (but only the top layer of paper) down, so that it touches the bottom edge. Now, fold the two side corners in, so it touches the folded down part. I think of it to look like an envelope during this step. At this point, unfold those to edges, and pull them up, and tuck them in where we folded down the top corner. Here, it should look like a diamond with a pocket.
Flip it over so the pocket is on the back, and now simply cut the top curves of a heart onto the top part.
