To begin our origami heart tutorial, we must start with a square paper. If you have a retangle, fold one corner down to meet the opposite side, then cut off the bottom to leave a triangle. Next, unfold the paper to reveal a square. The first step is to fold the paper in half and create a center crease in it, then unfold it.
Next, turn the sheet of paper so that it is open with the fold crease line running vertically. Fold up the bottom of the paper about ¼ of an inch. Then use that new folded edge as the new bottom of the paper, and fold the paper in half horizontally.
Making sure the open part of the fold is at the top, fold the top right corner to the bottom edge, bottom corner, to form a triangle on one side.
Do the same on the other left side with the top left corner folded down to the bottom edge to form a matching triangle on the other side. The whole paper now looks a bit like the roof of a house.
Working with the top layer of paper, take the bottom middle corner of the triangle on the right side and fold so that the edge lines up with the top triangle edge. Do the same on the other side, creasing hard. Then unfold both of those folds leaving the crease marks.
Starting with the lower left tip of the paper, fold it to meet up with the crease line you just created, on the middle edge. Do the same with the other side.
Next, open up the open edge of the triangle you just created on top, and tuck the piece of paper from underneath into it. Crease it hard. Do the same on the other side.
Then fold in the edges of the top four corners just slightly to make the whole shape more heart shaped.
Lastly you're going to blow some air with your mouth into the bottom point of the heart to inflate it, while using your finger to gently push down the centre and form the heart shape.
Notes
You can make a paper origami heart in any size, but to begin with I wouldn't make it too small or too big. Our paper here is about 4 inches square.Top Top: You could use any square piece of paper for this project, as long as it's not too thick, since thicker paper can be difficult to fold precisely. Card stock is not the best choice for this craft.
