Coloring tips
- Try using bright yellow for the main body of the submarine and a light blue for the round glass windows.
- This drawing is perfect for toddlers and preschoolers aged 2-4 because of its very thick lines and large open spaces.
- Focus on staying inside the thick black lines to help develop fine motor skills and hand-eye coordination.
