I thought of a neat trick for inserting lifelines into narrow pieces of lace work. I knit the last row with one of my interchangeable needles (not attached to a cable, just the needle with the threaded hole in the other end). Then I take that cotton cord, tie a knot in the end, and poke a new needle into the knot. Then poke it into the threaded end of the interchangeable needle, and push the new needle and lifeline into those stitches, pushing out the interchangeable needle. It takes a little care to do, but it's much faster than running a needle through!
