Do you mean micro stippling, or very tight, small stipples? If so, here is a U Tube video that may help:

I've found Karen McTavish's book and video "Mastering the Art of McTavishing" very helpful; in the video, she does micro stippling on an applique quilt and it's very easy to see what she's doing.
Good Luck!
