Several articles talk about the Crusaders bringing back quilts from the Near East; however, Marco Polo did go to China and quilted armour was used by Chinese, Japanese, and Islamic warriors throughout the medieval period.
Our humanities book by Gloria Fiero does cover quilting as a popular folkart, mentioning the famous Underground Railway quilts, coded to let runaway slaves know which houses were safe houses on their journey north to freedom and Canada. So, quilts have a very long history, both practical and beautiful. Sorry, no pictures. Kateryn's document has them in PDF.
