shrinky dinks yes
moondancer, fizzy, starshine, seashell, gypsy, medley, applejack, firefly, bubbles.
most of these are for sale. the ones on blue sold at the pony meet. i have to get some pictures of what they look on keychains/jewelry/etc. they're about the size of a quarter maybe?
i take commissions for these too (personas, hasbro ponies, and really any human/animal/object you could want).
