Is there a stitch length that is consistent for you? If so, then practice this length until you are really comfortanble, then begin to gradualy shorten the length In judging quilts it is often the consistency that is more important and not the length. Don't try to get 20 stitches to the inch or fill the needle. If one stitch will give you the consistency then do one stitch and then gradually add stitches to the needle or whatever but go bigger and gradually work down.
