There's sort of good news: Finally, I might have found an artisan who is capable and willing to reproduce medieval gold thread for me. Real, no-compromise gold thread, as it was found in the excavations at Villach-Judendorf in Austria: Gilt silver wound around a natural-coloured silk "soul", 0,2 mm thick and used for weaving (brocade) as well as for embroidery. (You can use several threads at once when doing couch work - I have a nice photo somewhere showing just that. After all, medieval people had their lazy streak too!)
"Normal" gilt or gold threads are imitation gold, wound around a core of cellulose or other material, but not around silk. And getting gilt-silver threads (not the japanese version, where a strip of paper is gilded or silvered) is really hard already, even if it's "just" gilt, not pure gold. Those threads are usually much thicker, too.
The downside? There's a hefty minimum order, and gold thread is not cheap. Quite the opposite, actually: Real gold or gilt thread was exquisitely expensive in the Middle Ages and it's still exquisitely expensive today. I'm very, very tempted to order the thread, but it's an investment that should not go too wrong.
So now it's time for me to play my most beloved game of them all (well, not really): "Guess The Market". And this time, I'm shamelessly using this blog to get some input from you, because I've been told time and again that I'm no normal textile stuff customer (though you probably aren't).
Do you feel the strong desire to buy authentic-to-the-soul gold thread? Modeled after a find? Even if it is really thin and really pricey? Would you use it for weaving, for embroidery, or for both? How much need do you have? And how much would you be willing to pay for, say, 10 metres? Or do you prefer to buy the cheaper imitation gold thread?
