hand or machine? It has been 20 years since I used Krenick? to hand quilt my Dear Jane, I learned quickly to thread 12-14" pieces or it wore through. Beautiful though, and worth it. Probably something much better out there now.
Machine applique I used gold or silver a lot, mettler. Worked great, occasionally I need to use a bit of silicone run down the length of the spool.
