Get your old shirt and draw an even number of circles. (I only needed 6 but you can use more. I suggest to not use less.) To make the circles you can use the bottom of a cup. Use your washable marker and draw.
Its alright if the circles aren't the same shape.
After you have them cut out pinch them in the middle. Start to bring the sides to the middle.
make your felt or poster board into about the size of a quater. add some gluw to the middle.
Start to glue them in the middle around the first one.
Its should start to look a little bit like this.
tadda! you can add a bobby pin or glue it to a headband. if you need any help just ask(:
