What are your experiences with sewing when running two threads through the eye of a single needle? Is this done for strength in lieu of a single thicker thread? Or maybe it's done because it has a desired visual effect, or maybe use two different colors for the same reason? I'd guess a topstitch needle is needed with the larger eye? How about these single needles with two eyes in tandem? Used for same purpose? Any special "tricks" used? Thanks for any opinions. JPBill
