Step 1: Draw the Wrench
Using a pencil, draw the outline of an open-end wrench on cardboard.

Smooth any rough edges before continuing.
Step 3: Make It Stronger
To create a durable toy:

- Glue both pieces together.
Press the layers flat until the glue dries.
This makes the wrench sturdier for repeated play.
Step 4: Cover the Wrench
