Pr 31:24 She maketh fine linen and selleth it, and delivereth girdles unto the merchants.
Girdles encircled the waist like a belt.
She helped bring in money to her household without neglecting all the other duties she had as a wife and mother. I wonder if she taught her children to work alongside her. I bet she did. She would want them to learn the skills they would need later in life. I doubt she would have been called virtuous if she neglected teaching her children the skills they would need later in life.
