Good plan! Through your marriage treaty, Scotland formed commercial agreements with the Low countries. You export locally produced goods such as wool and leather, then import luxuries from Europe to furnish your palace.
Trading flourishes and Scotland's burghs grow in size and importance. Edinburgh becomes a major burgh for Scottish trade with Europe.
Many luxuries are imported to Scotland. Wine from Bordeaux, linen and cloth from Flanders and other fine products from Lübeck.
