Oh those are so beautiful; I really love deep, rich colors.
This is probably a dull concept, but would it be possible to make this jewelry in balls in lieu of hearts? I'd love to purchase some for myself, but I tend to wear conservative jewelry/clothes due to my profession (and age, lol), so hearts or peacocks or the other wonderful oragami you do wouldn't be appropriate, as amazing as it is.
If not, I might just purchase something already 'in stock' and add some fun and color to my wardrobe.
