I used two different colored pieces of paper to make this (green and white). It's very easy and quick to make, and the result looks amazing. :)
Note: I tried to use some paper that was less thick and the bird looked okay, but the tail couldn't really hold its shape. I suggest sticking to printer paper or any other paper that is as thick.
Cardigan clips, sweater guards, collar clips… call them what you like, anyone can make a pair: here's how!
