I have meant for a long time to have a tie photo blog, where I would record every tie I wore, every day. I've finally got round to it, and created a tie set in Flickr.
I shall add to it every day I wear a tie, with notes on provenance, knot, and sometimes the reason I chose the tie. The pictures are so far all taken with an iPhone. Readers who would like to investigate the fascinating topological theory behind tie knots, as well as understanding the history and the more practical aspects of tying them are recommended to read the following:
