The back stitch is a beautiful stitch. I have a book on handquilting that says the back stitch is just as "acceptable" as the running stitch.
I cheat and use something I got from Tractor Supply, but I bought a pair at Harbor Freight. It is a pair of spring loaded needle nosed pliers, and the nose is curved upward. It has serrated teeth on the nose and the handle is padded. It is perfect for me to make a running stitch, load my needle, and pull it through with the pliers. It was awkward at first, but now I quilt as fast as anyone else.
Also, I don't use a frame at all. It makes the quilt easier for me to manipulate.
