Here are the steps to curl a bob:

1. Start by washing your hair and applying smoothing products to damp hair.
2. Divide your hair into sections of 1-2 inches wide.
3. Place one finger at the end of a section of hair.
4. Wrap your hair around your finger until you reach the roots.
5. Slide your finger out and secure your curl at your roots with a bobby pin.
6. Repeat steps 3-5 for all sections of hair.
7. Leave the bobby pins in place for 1-2 hours or until your hair is completely dry.
8. Remove the bobby pins and gently comb through your curls with your fingers.
