Assembly
Once the cards are cut re-crease all the fold lines. Then glue each single heart to the double heart that is the same size. Be careful to only glue the single heart below the fold line on the double heart. If you glue above the fold line the easel won’t work properly.
Next attach the letters to the top of each piece. The tiny heart is attached inside the smallest heart with a little piece of foam tape about 1 inch above the point. This acts as a stopper to the small heart easel.
The most difficult part of this card was deciding how much space to put between the hearts. But I am going to give you my measurements.
The easiest way to do this is open all the hearts and lay them on top of each other back sides up with the smallest heart on the bottom. The bottom of the smallest heart is glued inside the middle heart 1.25 inches below the point on the middle heart. The middle heart is glued inside the large heart 2 inches below the point on the large heart. Be sure to glue the hearts almost all the way to the middle fold on the smaller heart.
The inside point (at the top of the heart) of each heart acts a the stopper to the larger heart behind it. Here is a picture of the side view so you can see how they go together.
