I Have A Few Questions About My First Dino Mask

It's one of the hard plastic ones btw.

For the ears I'm using 1 inch poly foam and fur. Should I glue the fur to the foam or sew it? And then attaching the foam to the mask, should I use rubber cement(it doesn't dissolve the foam, I checked) or hot glue, or something else? Does anyone have any tips for painting the mask? I'm using acrylics.

Tysm!!!

I'll post results when it's done
