October 2025: 16,046 files released at the National Archives, three-quarters of which are WW2 WO records (how many still to go?!)

Lots of FCO files on Hong Kong from 1995 (two years before handover, so a busy time)

But which new file from August-October 2025 looks most curious…?
November 5, 2025 at 1:29 PM
September 2025: 14,749 files released at the National Archives, again lots of WW2 War Office records.

Also hundreds of MoD local maps of Northern Irish towns and borders, from 1969 onwards.

Plus thousands of born-digital Land Registry docs, including this excitingly self-referential one

August 2025: 16,013 files, 6095 of which are WW2 War Office personnel files, plus thousands of defunct company records, the oldest dating from 1864:

That’s the end of this, ahem, long synthetic 🧵of things I’ve seen at the British Textile Biennial

Credit to all the inspiring work of curators, artists and teams behind #btb25

5) also at Haworth Art Gallery: a room of Ivan Forde’s works. He’s from New York, and does frankly amazing things with cyanotype, using materials repurposed from marine waste with Bionic Yarn

Terylene was also marketed at men

Knife-edges on ledges!

A rave on the ocean wave!

Here’s me, 1977, wearing Crimplene trousers (stars? flowers?) looking into a pond in a wood outside Stevenage

(I still look into ponds quite a lot)

You may, if you are of a certain age, react nostalgically to the Terylene and Crimplene sample designs and colours

These are from Lancaster printers Standfast and Barracks, mid-1960s

“Who says a girl’s a tender flower
You won’t find us in an ivory tower
Breakaway girls don’t stay home with the chattels
They’ve got Bri-Nylon to win their battles”

(“Bri-Nylon” = British Nylon, another patriotically branded synthetic fibre. This time associated with, um, Norman invasion?)

Lots of interesting objects.

Here’s Ermen and Roby’s Terylene sewing thread

(Ermen & Roby used to be Ermen & Engels.

Engels as in Friedrich Engels)
