I have had pretty good luck with the Mettler Metallic 40 wt. and Thread Heaven. Also the Guttermann gold metallic with the Thread Heaven. Also had to be sure that I only cut and hand quilted with an 18" length. Haven't gotten good ("brave") enough on my FMC or just straight stitching to try the metallic, but that is on my to-do list. If push comes to shove you can always go with a yellow thread as close to gold as possible, and if you used a rayon thread it would give some sparkle.
