Needed items: 

- white modeling clay

- toothpick 

How to do it?

1. We knead and process the white modeling clay. We make a cone, for a length of about 8 cm. From the conical side, make a small hook and thread on the toothpick. We're entangling polymerine around the toothpicks. We model the tip of the shell so that it has a hole, like a real shell.
