This is a tricky little an offset hexagon stars tessellation. The idea is pretty basic. Just the stars and then some rhombuses. Folding it, however, is a little more complicated. 

The shapes that fill in the gaps on the reverse side are somewhat unusual. Actually, it's more how you have to twist them rather than the shapes themselves. 

I've been messing around with less standard tessellation techniques lately. Really searching for unique ideas and arrangements. 

I certainly could've done a better job in my execution. Perhaps a second attempt at another time will yield a more impressive final result. 


Still, the idea is intriguing.
