Popular Victoria Line fabric
I noticed that my photo of some London Underground Victoria Line seat fabric has had (as of today) 294 views on Flickr, and has been favourited 3 times. To me, that's a surprising amount of attention for something so... everyday.
You can actually buy this fabric at the London Transport Museum Shop. It's called "moquette" which is a type of woven pile fabric in which cut or uncut threads form a short dense cut or loop pile. As well as giving it a distinctive velvet-like feel, the pile construction is particularly hard wearing and ideally suited to applications such as on public transport.
