Draw something like that in a cardboard

Then, cut it

Do 2 small holes at the corners

And put 2 rings

After that, insert the string

If you want paint it

You will need pistachio shells too Wash it and then paint

I use nail polish but you can use acrylic or any type of paint

Like this

Use many colors

Finally it's time to paste

You will have this

If you want cut the remaining and tadaaa!
