Materials Needed:

  • A square piece of paper

Step 1: Create Your Square

If your paper isn’t already a square, start by cutting it into an even square shape. This will ensure your folds are accurate and your heart turns out symmetrical.

Step 2: Fold in Half

Fold your square paper in half horizontally and crease it well. Then open it back up.

Step 3: Add a Bottom Fold

Fold a small amount of the bottom edge upwards. This should only be a tiny fold—just enough to act as a guide for future steps.

Step 4: Fold in Half Again

Now, fold the entire square in half horizontally, bringing the folded bottom edge to meet the unfolded top edge. Crease it firmly.

Step 5: Shape the Heart’s Tip

With the bottom edge folded, bring the top corners down to meet the center of the folded bottom edge. This will create a triangular shape. Make sure your folds are neat and precise.

Step 6: Check Your Triangle

After folding the corners, your paper should resemble a triangle. It’s okay if the tip at the bottom is slightly flat; this is where you’ll blow in air later.

Step 7: Fold the Inside Points

Fold up the inside points on both sides of the triangle to create a guide for your next folds. These guidelines will help shape the heart.

Step 8: Fold the Bottom Corners

Fold the bottom corners inward so that the tips meet the guidelines you just created. This step starts to form the rounded edges of the heart.

Step 9: Tuck the Paper

Fold up the inside flaps and tuck them into the triangular pockets you created in the previous step. This secures the folds and shapes the heart.

Step 10: Round the Heart

Flip your heart over so that the flat tip is on the bottom. Fold the top corners inward slightly to round out the top of the heart. This step gives it a softer, more natural shape.

Step 11: Puff Up Your Heart

Gently blow into the opening at the bottom tip of the heart. If you’ve folded everything correctly, your heart will puff up beautifully!
