What is Valentine's Day without one of Francis Ow's hearts? So here you go, Ow's Double Hearts.

The 2 hearts are made from half a square and each heart displays one side of the paper. So naturally, double sided paper with contrasting colours work best.

I used a double-sided 120 gsm 8-inch paper cut into 2. This was the only double-sided paper I had, so had to make do. But regardless, I was able to make the origami. So yay!!

The XYZ Diamonds is another planar origami model, made from 3 intersecting diamonds. The design is by Francis Ow, the well known folder/creator of origami hearts.

Though it looks like there are only 3 planes, joined in the middle as though by magic(!), the planar model is actually made of 6 modules. Accuracy is required in folding the modules, else fitting each unit into the next is almost impossible. The first 4 modules can be fitted in easily. The last 2 are not that easy and this is where accuracy of folds makes a difference.

The model works best with 3 colours and 2 modules of each colour.
