Why did carding go to the lowland when it was not yet market day?

Carding likely went to the lowland before market day to prepare and process wool or other fibers in advance, ensuring that the material was ready for sale or further crafting. This early preparation would allow for a more efficient use of time and resources, helping artisans or traders maximize their productivity. Additionally, it may have been a strategic move to establish a presence in the lowland area, attracting potential buyers ahead of the market day.
