Here's a stack of links to various topics:

A Youtube video of a lecture given by Randy Pausch on how to achieve your Childhood Dreams.

A method on how to get vegetable matter out of wool, using a hand card - it's a rather time-consuming method from the looks of it, but a very interesting way to clean fibres.

An article on apparel for athletic activities from the 14th to the 19th century - open access (yay!).

Finally, in case you are in Scotland and interested in natural colours, there is a talk and workshop on Turkey Red on Saturday, March 2, 10 to 12:00 at Dumbarton Library.
