When you are going to make a parakeet hat you should use two color.
After you finished crocheting the hat it is time for cutting out all parts in felt. You need;
2 white circles and 2 black circles for the eyes
1 brownish orange triangle for the beak
1 eight-shaped part for the top of the beak and
2 small ovals for the holes on the beak.
Now lay them out on the hat so you know where you want them. Pin them in right spot and sew them on with a thin tread in matching color.
Tips, Remember the eyes are going to move apart more when you put on the hat.
