Avoid using small pieces of paper on your first try, as the folds will be more difficult to make and this may be frustrating. If you’d like to make a larger sized heart, use a larger piece of paper. If you decide to draw a design, split it in half; it will end up in the center of the heart. A decoration can be added when the heart is finished as well.
If you are using A4 paper as opposed to origami paper (which has a white side), don’t worry about turning the paper to the side that is white.
Make sharp folds by sliding your nail over each fold. Neat, sharp folds will make your final product look better.
It can take several tries to create the pyramid shape, especially if you are new to origami. You should end up with what looks like a triangle sitting on top of the rectangular portion at the bottom.
