sun spike cp
understanding oripa is much easier than I'd thought : )
this cp might be used with a bit of caution. I drew it just from the pictures of the sun spike because I'd already given the actual model away to my grandparents.
the square decorations are where they should be.
I am not 100% sure about the the inner blue star which makes the spike come upwards, though. actually when folding the model I improvised the angle of the spike. finally a bit of simulation in tomohiro tachi's freeform origami suggested that the way it is now should yield a nice model.
