Framed Heart (variant B)

This is variant B of my Framed Heart. Just like the original, it consists of a tessellation molecule placed inside a frame folded from the same sheet of paper. Variant B differs from variant A in that it is more paper effective: the heart itself only uses a 14×12 grid rather than 14×14. Another improvement is having just one horizontal hidden pleat instead of two and thus a cleaner background.

These improvements come at a price, however. While using a little less paper may be an advantage when folding a big tessellation, when folding a single molecule inside a symmetric frame, using a grid of same width and height makes folding from a square simple. When the molecule uses a non-square area of the sheet, excess paper needs to be hidden behind the frame, so simply using it for the molecule would have been more convenient. Another problem with this variant is that using less paper causes the heart to be locked to the background much stronger than in variant A. This means that it is not possible to shape this heart to make it look as round as is possible with variant A since the vertices of the heart are attached to the background.

Nonetheless, this variant is interesting too, and in some cases its better paper efficiency is useful indeed, as was the case when I used this molecule as decoration for a modular origami cube and the two grid units gained in one direction were exactly the amount of paper I needed to create small tabs necessary for connecting the units.
