I think they're called Self-Threaded Needles. I don't have the packaging anymore.
Yep, that's what they're called.

I think I got mine at Houston, but I'm sure they are made by many companies.
If you look closely, you'll see the top is shaped a bit differently. It has a slit in it, and it allows you to just "pop" the thread in. And then you can sew with it.
Personally, I don't recommend using it for regular sewing - I did the binding on a quilt with it and really cut up my fingers.
Those are sharp points on top.
But to use it to bury threads - such a pleasure.
And makes the whole process go quickly.
And then there's this one:

Very cool looking, but a lot pricier. It's actually the only pop-up I ever saw here that was interesting enough to click through to see more. ;-)
