In 2009, I visited the Monastero de Santa Maria la Real de las Huelgas:
The monastery was wonderful, but what really wowed me was an exhibition of medieval fabrics from the 13th and 14th centuries. It made me wonder what kinds of fabrics were available in the 12th century when Ermengarde lived.
I began studying the clothing in medieval manuscript illuminations and frescos and found a wealth of sophisticated fabrics and designs.
You can see some of the richness by looking at the photos on Wiki. Great stuff!
