I love using these blunt end needles when sewing various coptic stitch books. My only suggestions would be 1) make the needles a little longer 2) package them with three of the same size instead of three needles of different sizes. Usually I use six of these needles per book, so I would rather buy two packs containing three of the same size needle rather than six packs that only have one of the size needle I need.
