More awesome origami from my sister

Fancy purple geometric origami

My sister just sent me this awesomely complicated origami (the purple one above). You can read about how she makes them here. Although this specific one isn’t there, I don’t know how she did it. I suspect mathematical wizardry.

The one below isn’t as complicated but I think it is very pretty because of the patterned paper. I have had this one for a while. If I remember correctly my sister folded all the bits of paper and let me put it together. What a nice big sister.
