Two Hearts Framed

I designed this model as a wedding gift, starting out from my Framed Heart model.
Due to the two hearts’ proximity, the collapse is rather difficult. This pattern can be tessellated, but a single framed molecule was already quite challenging. It gets easier if the whole grid is precreased, but that results in the grid being visible on the hearts and the background. I am generally quite happy about this model except for the lock which holds the final crease which brings one heart on top of the other: there are too many layers of paper in that area, and I was not able to fold this part in a completely neat way. While it’s not obvious in the picture, the many layers cause the center of the model to buckle instead of staying flat.
