This is an easy little project I did when I was a little bored :P

Just cut out what you want, glue it together and add the bobby pin to the back.
What I did to make sure it stayed was I got another bit of felt, cut two small slits for the bobby pin to slide through and put a little glue on the bobby pin top. Then when I slid the top of the bobby pin into the slits, glued it onto the back of the "emote" and it stuck very well :3
