I have finished the first pair of royal gloves for Their Stellar Majesties Ulsted the Unsteady and Ebergardis von Zell. The stitching is done in German Brickwork and is Rainbow Gallery Splendor silk on linen, with Kreinik Japan Gold #7 couched as outlines. I sewed the stitched roundels onto the gloves using a leather awl and the trim is braided Kreinik Japan Gold #7. The gloves were delivered at Bryn Gwlad's Candlemas event.
Since I was attaching the stitched roundels to leather gloves, I rummaged through my toolbox and found my leather awl. It was definitely the right way to go, especially since the gloves were already put together and I had to reach inside them. The German brickwork stitching has a lot of body when finished, which makes for a really thick finished piece. Even with some tight stitching on the edges I found that I needed a thick trim to keep the edge from being too abrupt.
I tried several different approaches to the trim. I think that finger loop braiding can make really nice trim, so I tried a few different patterns and discovered that Japan gold is terrible for finger loop braiding. It doesn't hold tension well, stretches unevenly, and doesn't flex gracefully - so you end up with a chunky mess that glitters. I was going for something a bit more elegant than that so I tried several flat braids. The final winner was a three strand flat braid with 6 pieces of Japan gold per strand - 18 total strands. The result was a smooth trim which (with some fiddling) I got to lay at a (mostly) 45 degree angle to smooth the chunky edges.
