a 'Tapestry' trim source, or leads?

[Malcolm Parker]

Proper moquette is like a very thin carpet, with the surface made up of tiny loops of thread.   As they say in Yorkshire, it 'wears like pin wire', which is why it was used extensively for bus and railway carriage seats.
There is uncut and cut moquette. The stuff I used is uncut.  When it is cut the surface is cut away in a pattern, often a 'Paisley' or similar.
