I'm doing some research into African textiles and the museum has a great African gallery, took lots of photos.
This 'foil quilt' is made from the torn foil that surrounds wine bottle tops. It's so colourful and is on the wall as you go into the gallery.
There was a short film about Kangas - a form of clothing worn by both men (around the house) and women (at all times). There is a very comprehensive history of the kanga at http://www.glcom.com/hassan/kanga_history.html Copy and paste this link into your browser to view if you don't have a direct link. Wikipedia has a shorter definition of the word kanga. The picture below is from Wikipedia http://en.wikipedia.org/wiki/Kanga_(African_garment)
