Well, as I can't pick a craft and stick to it, here are my first two perler coasters, a Sonic the hedgehog and a Sora from Kingdom Hearts (chain of memories).
Sonic is best, show I'll show it first even though it isn't.
not much to say other than the background are translucent suncatcher beads, so it looks nice propped up against my window.
Well, as my very first, this one is kinda sloppy and unattractive, the translucent beads are just randomly in the face, and so on. BUT it's distinguishably Sora, which motivated me not to quit.
