So the major challenge in my quest to recreate the specific look of Kristina Gyllenstierna from the 1516 altarpiece in Västerås is to figure out her headpiece.
Altarpiece with the Martyrdom of St Catharine: St Dorothea, St Agnes, St Kunigunde [left wing, recto]
It's obvious that the decorations come from gold embroidery, and that is the reason why I have spent quite some time this year practising gold embroidery, and now I'm waiting for my material to arrive. Under all the embroidery there are the diamonds made up from dots though. They continue under the embroidery so they must on the fabric itself. I couldn't find any fabric with that pattern, so I would have to do it myself. After having totally overthought it, I had plans to basically build a full printing set up, I realised that the easiest way of doing a fairly similar pattern would be with a marker pen.
And here is the final result - linen fabric with diamonds built up from gold dots.
