With a million threads to bury on that beast of a quilt I pulled out these needles. They were part of some swag in the Denyse Schmidt Improv class from QuiltCon and they originally come from Purl Soho. I put them aside after trying them for binding. (Not a good use there - it cut the thread sometimes and was thick for getting through the small edge of the binding.) But I find them absolutely perfect for burying threads.
I must admit, I never used to bury my threads. I just stitched once or twice where I started then cut flush. Frankly, I was lazy. But the finished look was nowhere near as neat. So now I spend the evening burying threads and am much happier with the finished results. I do tend to wait until I'm done all the quilting so it can add up to a fair amount of work, but I find it easier and it doesn't break with my machine quilting rhythm.
I do exactly the same technique as Amanda. And these easy thread needles are perfect for it. They save you trying to thread two threads into the eye of the needle, and having sit awkwardly in order to use your eye, at eye height, to thread what are likely to be short threads attached to a heavy quilt.
Oh, and in case you were wondering about the intensity of that quilting, here is my thread. Can you see it? That's 1000 meters of thread per spool! I used one whole spool and then some.
