I covered the felt with silk, as some of the centre of each arm will be visible, then put more felt on top of this around the edge of each arm. Still two arms to stitch on, but I stitched on the first gold!
Well, there's not much to show on the goldwork front so far. I've got the silk stitched on and everything tightened up on the frame. Only I forgot to pin tissue paper on. I've decided that's a job for another day!
