I pretty much agree with what these two ladies have said. I use my nails if they are available..........sometimes a thimble. I do the rocking stitch. I'm not sure what the stab stitch is---??? I've used it to go thru thick seams or such, but when "I" do it, they are not small and even, so it must be another technique I can't quite picture in my brain.
About needles, I use the needles from "Thimblelady" in Austrailia. They are very fine and quite a bit longer than most quilting needles. They hold more like 6-8-12 stitches at a time so speeds up the process quite a bit for me. I will say, they are not as "strong" as American or English needles so if you tend to bend needles, these probably won't work for you. I've done several quilts on 1 package of needles, so I guess I've learned not to over torque them.
I hope this helps. Alot of it is trial and error, I'm afraid!
