I get the Jeane Kimball's Foxglove Cottage needles at my LQS.. have also seen them on line. Right now there are probably 12 needles on each of 3 different spools of quilting threads in my box. I was doing some piecing last night and when I pulled off the "next length" of thread noticed that the needle was "chunky" guess I got a few of another brand mixed in with them.
I was soooooooo obvious stitching with it. Also I'm pretty sure that you could not use a needle threader with these I've never seen one thin enough to go through the eye.a single length of thread will barely go through, let alone a double.
