The sequin/button motif I also added, plus the little lace flowers above it, the gold fly-stitch seam to the left, and some rachelette woven into the lace below. Wherever I could find a few centimeters, LOL!!
The lace butterfly in the upper right had some pale chain stitching on the wings already. I added more gold chain stitching, plus outlined the butterfly in a gold backstitch to emphasize it more without adding any visual weight. And some pearls for the antennae. That lovely bead ribbon above the butterfly was done by Cobi. The finished block is below.
