I can get Organ needles from All Brands (we have a local outlet here). As far as the thread goes, my PE-770 does not like the red threads from DesignsbySick. I have to use Robison-Anton or possibly Coats & Clark, but it sometimes doesn't like the Coats & Clark. I got a large spool of red embroidery thread at a flea market, and it has no problem there. Can't explain why it just doesn't like certain red threads.
