I totally agree with GrammaBabs when she says,
"Another tip.. for me.. the whole "stipple thing" is just not possible.... i have no problem doing what i call a loop de loop..one loop goes up... the next goes down... that seems to be a movement that comes natural to me."
I find I'm concentrating too much on not crossing lines of stitching and trying to decide where to go next and keep the stipple in a relatively same size. I'm more comfortable with something that feels like handwriting. Maybe it's from so many years of "Palmer Method", handwriting with the nuns!!!
I do keep trying to stiple though! Never was great at penmanship.
