well well, I've made today my Chii ears, and I took some pics, maybe they'll be usefull for someone that think that the already made ears are too expensive, or can't get them for... any reason (like me
first you have to cut the material (I don't know the name of it, sorry) in this shapes
Then you make a cone with the pink part
and you glue it tho the white part
be sure to use an efficient instant dry glue, because if you use normal white glue... you'll have to wait with the ear in your hand till it's completely dry.
