A more thorough explanation:

The Board of Green Cloth was a group of people responsible for managing the finances of the royal household staff. This included accounting for expenses and paying the wages of servants. The Board was made up of the Lord Steward and other officers, and was named after the green cloth that covered the table where they conducted their duties.

In the past, the Board also had the responsibility of keeping the peace and maintaining courts of justice within the area around the royal household, known as the verge.

For example, if a servant needed to be paid, they would go to the Board of Green Cloth to receive their wages. The Board would also keep track of how much money was being spent on things like food and clothing for the royal household.

Overall, the Board of Green Cloth played an important role in managing the finances of the royal household and ensuring that everything ran smoothly.
