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
