from artist:  
“Designed and folded by me from 25cm square blue double tissue.
 
Paper version of the infamous blue flower from MLP:FIM. Since canon poison joke was pretty vague on the actual number of petals the flower actually has, I went with five petals. With the way I distributed the paper, this was a happy medium between: four stamens and four petals(too few imo) or two stamens(too few) and six petals. The inner set of petals was also a sort of compromise; I had originally planned to make another set of petals for the inside, but I couldn’t find an efficient way to do it.
 
There’s probably a similar design out there as 5 petal flowers aren’t anything new. However, hopefully this variant hasn’t been done before.
